According to Gauss's theorem the net-outward normal electric flux through any closed surface of any shape is equivalent to 1/ε0 times the total amount of charge contained within that surface. Gauss's Law. The total of the electric flux out of a closed surface is equal to the charge enclosed divided by the permittivity. The electric flux through an area is defined as the electric field multiplied by the area of the surface projected in a plane perpendicular to the field. 

Derivation of Gauss's Theorem: Let +q charge is placed at a point O and a point P lies at distance r from the point O. Therefore, the intensity of electric field on the surface at all the points will be equal in magnitude and will be directed radially outward. ∴ The electric flux passing through the spherical surface.

Torque =pEsin© where ©=angle between p and E p=torque/Esin©=9×10^-25×2/10^-4=18×10^-21 Nm

Utkarsh Srivastav 5 years, 3 months ago

Hello ? kuhu

Rohit Krishna 5 years, 3 months ago

Use the equation for torque, Torque=P.E=PEsin theta, where P is the dipole moment, E is the electric field and theta is the angle between dipole and the field.From this you substitute the values given above to find the dipole moment of the electric dipole. ie,. 9 * 10^-25 = P * 10^4 * sin30° =P * 10^4 * 1/2 = P * 5 * 10^3 .Therefore, P= 9 * 10^-25/5 * 10^3 = 1.8 * 10 ^-28 Cm.I hope this is the answer......If not then I'm sorry.

Repulsion is the surest test for charge bcoz repulsion occur between charged bodies only whereas attraction is present between both charged as well as uncharged body (due to gravitational force)

😜Arnav Arya🙃 5 years, 3 months ago

I think you should understand the concept of ELECTROSCOPE it would help u to clear your doubt

Yogita Ingle 5 years, 3 months ago

The charged body conducts charge to an uncharged body through the transfer of electrons according to the charge on the charged body. Due to induction of opposite charge on the uncharged body, both will be in attraction and thus, the uncharged body will remain in question of the possession of charge.

Pair production is the creation of an elementary particle and its antiparticle, for example creating an electron and positron, a muon and antimuon, or a proton and antiproton. Pair production often refers specifically to a photon creating an electron-positron pair near a nucleus but can more generally refer to any neutral boson creating a particle-antiparticle pair. In order for pair production to occur, the incoming energy of the interaction must be above a threshold in order to create the pair, at least the total rest mass energy of the two particles and that the situation allows, both energy and momentum to be conserved.There exists an inverse process to pair production called pair annihilation, in which a particle and its antiparticle collide and annihilate each other, the total energy of the two particles appearing as electromagnetic radiation.

Yogita Ingle 5 years, 3 months ago

The conversion of a photon into an electron-positron pair on its interaction with the strong electric field surrounding a nucleus is called pair production.
The converse of pair production in which an electron and positron combine to produce two photons is known as annihilation of matter.

It deals with study of current at rest

Meghna Thapar 5 years, 3 months ago

Electrostatics is a branch of physics that studies electric charges at rest. Since classical physics, it has been known that some materials, such as amber, attract lightweight particles after rubbing. Electrostatics (also known as static electricity) is the branch of physics that deals with apparently stationary electric charges. Electrostatics involves the buildup of charge on the surface of objects due to contact with other surfaces.

The formula for electric dipole moment for a pair of equal & opposite charges is p = qd, the magnitude of the charges multiplied by the distance between the two. Electric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge and radially in toward a negative point charge.

Magnetic Flux is defined as the number of magnetic field lines passing through a given closed surface. It gives the measurement of the total magnetic field that passes through a given surface area. Magnetic flux is what generates the field around a magnetic material. ... The number of magnetic field lines passing through a surface (such as a loop of wire). The magnetic flux through a closed surface (such as a ball) is always zero. The SI unit of magnetic flux is the Weber (Wb) (in derived units: volt-seconds).

The electric charge that has been separated creates an electric potential difference that can be measured with a voltmeter between the terminals of the device. The magnitude of the emf for the battery (or other source) is the value of this 'open circuit' voltage. The current can be found from Ohm's Law, V = IR. The V is the battery voltage, so if R can be determined then the current can be calculated. The electromotive force (e) or e.m.f. is the energy provided by a cell or battery per coulomb of charge passing through it, it is measured in volts (V). It is equal to the potential difference across the terminals of the cell when no current is flowing.

Recharging a battery involves the conversion of electrical energy to chemical energy. During recharging, there is movement of electrons from an external power source to the anode, and on the other side electrons are removed from the cathode. Rechargeable cells and batteries can be recharged because the chemical reactions can continue because an electrical current is supplied.

An erect image, in optics, is one that appears right-side up. An erect image is formed when both rays intersect each other at a certain point. It is an image in which directions are the same as those in the object, in contrast to an inverted image. It is one of the property of image formed in a plane mirror. In optics, an image is defined as the collection of focus points of light rays coming from an object. A real image is the collection of focus points actually made by converging rays, while a virtual image is the collection of focus points made by extensions of diverging rays. A real image occurs where rays converge, whereas a virtual image occurs where rays only appear to diverge. Real images can be produced by concave mirrors and converging lenses, only if the object is placed further away from the mirror/lens than the focal point, and this real image is inverted.

Value Of Epsilon Naught

The permittivity of free space(ε0) is the capability of the classical vacuum to permit the electric field. It as the definite defined value which can be approximated to

ε= 8.854187817 × 10-12 F.m-1 (In SI Unit)

Or

ε= 8.854187817 × 10-12 C2/N.m2 (In CGS units)

Gaurav Seth 5 years, 3 months ago

Epsilon Naught is synonymous to the permittivity of free space or absolute permittivity or electric constant, represented by the Greek alphabet ε0. The Epsilon Naught value is constant at any part of the universe. It is often miss used as value of Epsilon not. Permittivity is the measure of the opposition offered against the formation of an electric field.

With derivation in mathematically method

Meghna Thapar 5 years, 3 months ago

Coulomb's law states that: The magnitude of the electrostatic force of attraction or repulsion between two point charges is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them. The force is along the straight line joining them. The fact is that either you have to assume that coulomb's law is the result of gauss law and then it can be derived , The other one is it is a law and cannot be proved. Multiply by charge and net force is found out. Thus the Coulomb law is derived by assuming gauss law to be valid. Coulomb's law states that: “The force of attraction and repulsion between two point charges is directly proportional to product of their magnitudes and inversely proportional to the square of distance between them.” F=kq1q2/r^2.

Drift velocity is the average velocity that a particle such as electron attains in a material due to electric field. So it depends upon mobility. In physics, a drift velocity is the average velocity attained by charged particles, such as electrons, in a material due to an electric field. In general, an electron in a conductor will propagate randomly at the Fermi velocity, resulting in an average velocity of zero. The drift velocity does not depend on the length or the cross sectional area of the wire, when dealing with a macroscopic (ordinary, everyday life) wire.
