THEORY: inside the hollow sphere the potential at every point is constant and is equal to the potential at the surface
because electric field is zero inside the hollow sphere
new potential of small sphere when placed inside bigger sphere = potential due to bigger sphere + existing potential of the smaller sphere
new potential of smaller sphere = V + V/2 = 3V/2
new potential of bigger sphere = existing potential of bigger sphere + potential due to the smaller sphere ( at distance 2R potential due to small sphere will be V/4)
new potental of bigger sphere = V + V/4 = 5V/4
potental difference=new potential of smaller sphere – new potental of bigger sphere
pootential difference = V/4
