Question

Assertion (A): Equal amount of positive and negative charges are distributed uniformly on two halves of a thin circular ring as shown in figure. The resultant electric field at the centre O of the ring is along OC.

Reason (R): It is so because the net potential at O is not zero.

पर्याय

• If both Assertion (A) and Reason (R) are true and Reason (R) is correct explanation of Assertion (A).

• If both Assertion (A) and Reason (R) are true and Reason (R) is not the correct explanation of Assertion (A).

• If Assertion (A) is true but Reason (R) is false.

• If both Assertion (A) and Reason (R) are false.

Answer 1

If Assertion (A) is true but Reason (R) is false.

Explanation:

The electric field originates from positive charge to negative charge; hence, its direction will align with OC. The net potential at zero is also zero. Therefore, the assertion is true while the reason is false.
