Physics Question on electrostatic potential and capacitance
A hollow metal sphere of radius 10 cm is charged such that the potential on its surface becomes 80 V. The potential at the centre of the sphere is
A
80 V
B
800 V
C
8 V
D
zero
Answer
80 V
Explanation
Solution
The potential at the centre of the sphere is 80 V because it remains same at each point under the metallic hollow sphere
