Assertion (A): For identical charges of ...

Assertion (A): For identical charges of magnitude g each are placed at the vertices of a square of side'a'. The electric field at the centre point O is zero but electric potential is non-zero and finite. Reason
(R) : Electric field is a vector quantity but electric potential is a D scalar.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If the assertion is false but reason is true.

Text Solution

Verified by Experts

Electric fields due to diagonally opposite charges balance each other and net field at point O becomes zero. However, potentials due to all the charges are added up.
