    When the charges are kept in vacuum at a distance r,>>>>>Force F=kq1q2/r^2 where k=1/4π *epsilon not.Let this be equation 1>>>>>>When force is 8F,let distance between the charges be r". Therefore,Force 8F=kq1q2/r"^2. Let this be equation 2.>>>>>>> Now 1/2 gives,------>1/8=r"^2/r^2 and hence r"=r/2√2-----(taking square root on both sides)

    if q1 and q2 sperated at a distance r then force F1 =Kq1q2 ----------- r² if charges are halved that means q1/2 and q2/2 and the distance between them is doubled . then... let new force =F2 F2 = kq1/2 q2/2 --------------------- ( 2r)² => kq1q2 ----------- 4 -------------------- 4r² after cancellation you will get same i.e F1=F2

    The electromotive force is the measure of energy that it gives to each coulomb of charge, whereas the potential difference is the amount of energy used by the one coulomb of charge. The potential difference is the measure of energy between any two points on the circuit.

    Rohit Krishna 5 years, 4 months ago

    When a charge is placed on one of the corners of a cube,we need to consider a gaussian surface which completely encloses the charge in order to find the flux through the cube.So to enclose this charge at the corner,we need to place 8 cubes(7 cubes+ the first cube where the charge is placed) which are identical to the first one. • From gauss's law, Flux inside the big cube=q/epsilon not. Hence for 8 cubes the flux is given,therefore for a single cube flux=q/8*epsilon not.

    ? ? 5 years, 4 months ago

    Its just like your resistances ....where in series current in each resistance is same ....in capacitors in series charge on each cap is same....in parallel connection if the cap have same capacitance then each will have same charge as voltage is same for all....and the net charge of circuit will be sum of all charges ....but if variable capacitors are used then charge will get distributed in direct ratio of capacitance

    1Thank You

    Rohit Krishna 5 years, 4 months ago

    Sorry my question was not clear I guess. What I asked was about capacitors connected in parallel in a circuit.Why is the charge variable in different capacitors connected in parallel to an external circuit? If the capacitors are identical,what would be the charge distribution? I hope you understood the question.

    0Thank You

    ? ? 5 years, 4 months ago

    Charging of capacitor takes time , so in initial state it is charged zero while at steady state it is fully charged. Is this what you were asking? I didnt understand your ques properly.

    Rohit Krishna 5 years, 4 months ago

    In some materials,the outer electrons of each atom or molecule are weakly bound to it.These electrons are free to move throughout the material.When such a material is placed in an electric field, these electrons move in a direction opposite to the field.Such materials which conduct electricity are called conductors.
