- zero
- 10 V
- 4 V
- (10)/(3) V
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Property of conducting sphere. Inside a conductor, electric potential remains constant.
Step 2: Applying the concept. Potential at every interior point equals surface potential.
