The electrostatic potential at a point on the surface of a charged spherical conducting shell of radius 10 cm is 120 V. The electric potential at a distance of 5 cm from the centre of the shell is:
- A Zero
- B 30 V
- C 60 V
- D 120 V
Answer & Solution
Correct Answer
(D) 120 V
Step-by-step Solution
Detailed explanation
The electric potential inside a charged conducting spherical shell is constant and equal to the potential on its surface. \(V_{\text{inside}} = V_{\text{surface}} = 120 \text{ V}\)
