MCQ

Assertion : For a non-uniformly charged thin circular ring with net charge is zero, the electric field at any point on axis of the ring is zero.

Reason : For a non-uniformly charged thin circular ring with net charge zero, the electric potential at each point on axis of the ring is zero.

A
If both Assertion and Reason are correct and Reason is a correct explanation of Assertion.
B
If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion.
C
If Assertion is correct but Reason is incorrect.
✓
If Assertion is incorrect but Reason is correct.

✓

Answer

Correct option: D.

If Assertion is incorrect but Reason is correct.

d
For a non-uniformly charged thin circular ring with net zero charge, electric potential at each point on its axis is zero. Hence electric field at each point on its axis must be perpendicular to the axis. Therefore Assertion is incorrect and Reason is correct.
