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

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.

two metal spheres of radii R_(1) and R_(2) are charged to the same potential. The ratio of charges on the spheres is
