Equipotential spheres are drawn round a point charge. As we move away from charge will the spacing between two spheres having a constant potential difference decrease, increase or remain constant.

Equal charges are given to two spheres of different radii. The potential will

Equal charges are given to two spheres of different radii. The potential will

The ratio of the forces between two small spheres with constant charge 'a' in air and 'b' in a medium of dieletric constant k is

An isolated conducting sphere is given a positive charge. Does its mass increases, decreases or remains the same?

An isolated conducting sphere id given s positive charge. Does its mass increase, decrease or remain the same ?

Asseration: A point charge q is placed at centre of spherical cavity inside a spherical conductor as shown. Another point charge Q is placed outside the conductor as shown. Now as the point charge Q is pushed away from conductor, the potential difference (V_(A) - V_(B)) between two points A and B within the cavity of sphere remains constant. Reason: The electric field due to charges on outer surface of conductor and outside the conductor is zero at all points inside teh conductor.

What is the work done in moving a charge between two points on an equipotential surface?
