CUET Preparation Today
A hollow metal sphere of radius 5 cm is charged such that the potential on its surface is 10 volt. The potential at the center of the sphere is : |
zero 10 volt same as at a point 5 cm away from the surface same as a t point 25 cm away from the surface |
10 volt |
Electric potential at any point inside a hollow metallic sphere is constant. Therefore, if potential at surface is 10 volt, potential at centre will also be 10 volt. |
