A hollow metal sphere of radius 5 cm is charged such that the potential on its surface is 10 volts. The potential at the centre of the sphere is
A
Zero
B
10 V
C
Same as at a point 5 cm away from the surface
D
Same as at a point 25 cm away from the surface
Answer
10 V
Explanation
Solution
Inside the conductors potential remains same and it is equal to the potential of surface, so here potential at the centre of sphere will be 10 V
