Question

electric potential at a point P, R distance away due to point charge Q at point A is V .if twice of this charge is distributed uniformly on the surface of a hollow sphere of radius 4 R with centre at point A The potential at point P now is
a)V b)V/2 c)V/4 d)V/8

Answer 1

potential inside a hollow sphere remains constant and equal to the magnitude at surface.....
