No coulomb law is not applicable when the distance between two charges is more than 1Å

Sarvesh Kumar 5 years ago

Coulombs law is applicable for point charges only. Distance between two charges should not be more than the radius of the nucleus. Charges must be at rest.

Jyoti Soni 5 years ago

No ....columb law is valid for only point charges

Introducing a dielectric into a capacitor decreases the electric field, which decreases the voltage, which increases the capacitance. A capacitor with a dielectric stores the same charge as one without a dielectric, but at a lower voltage. Therefore a capacitor with a dielectric in it is more effective. The field produce due to the polarization of material minimize the effect of external field. Hence, the electric field inside a dielectric decreases when it is placed in an external electric field.

In the Fahrenheit scale, the freezing of water is defined at 32 degrees, while the boiling point of water is defined to be 212 degrees. The Fahrenheit scale measures temperature. It is based on a scale proposed in 1724 by physicist Daniel Gabriel Fahrenheit (1686-1736). The unit of this scale is the degree Fahrenheit (°F). On this scale, water’s freezing point is defined to be 32 degrees, while water’s boiling point is defined to be 212 degrees. The kelvin is a unit of measurement for temperature; the null point of the Kelvin scale is absolute zero, the lowest possible temperature. The kelvin is a unit of measurement for temperature. It is one of the seven base units in the International System of Units (SI) and is assigned the unit symbol K. The Kelvin scale is an absolute, thermodynamic temperature scale using absolute zero as its null point. In the classical description of thermodynamics, absolute zero is the temperature at which all thermal motion ceases.

Whenever, a current carrying conductor comes under a magnetic field, there will be a force acting on the conductor and on the other hand, if a conductor is forcefully brought under a magnetic field, there will be an induced current in that conductor. In both of the phenomenons, there is a relation between magnetic field, current and force. This relation is directionally determined by Fleming's Left Hand rule and Fleming's Right Hand rule respectively. Directionally means these rules do not show the magnitude but show the direction of any of the three parameters (magnetic field, current, force) if the direction of other two are known. Fleming's Left Hand rule is mainly applicable for electric motor and Fleming's Right Hand rule is mainly applicable for electric generator. In late 19th century, John Ambrose Fleming introduced both these rules and as per his name, the rules are well known as Fleming's left and right hand rule.

The dielectric constant is the ratio of the permittivity of a substance to the permittivity of free space. It is an expression of the extent to which a material concentrates electric flux, and is the electrical equivalent of relative magnetic permeability.

Shweta? Dhama? 5 years, 1 month ago

Dielectric constant of a material is the ratio of its permittivity of medium ε to the permittivity of vacuum ε o , so K= ε / ε o. The dielectric constant is therefore also known as the relative permittivity of the material. Since the dielectric constant is just a ratio of two similar quantities, it is dimensionless....

The dielectric constant (k) of a material is the ratio of its permittivity ε to the permittivity of vacuum ε o , so k = ε / ε o. The dielectric constant is therefore also known as the relative permittivity of the material.

The aim of the experiment is to study the emission of electrons by light. We also try and measure the energy of the electrons emitted in the process. In addition to this, we will also observe the relation of these electrons with the frequency of light used. To study the effect, we use an evacuated cathode ray tube connected in a circuit as shown below:

Suvarna ? 5 years, 1 month ago

The rate of flow of charges through a conductor of any cros section

? Yang ? 5 years, 1 month ago

Answer~ Electric current is basically the flow or charge of the electric charge in motion in a conductor. It is said to exist when there is a net flow of charge through the region. The current is given as the flow of charge per second: I = charge​/time. The SI unit of current is Ampere. HOPE IT HELPS YOU?✌
