easy

Can the potential function have a maximum or minimum in free space ? Explain.

Option A

Option B

Option C

Option D

Solution

No, the absence of atmosphere around conductor prevents the phenomenon of electric discharge or potential leakage. Hence, the potential function does not have a maximum or minimum in free space.
