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.
Official answer
(C)
Assertion (A) is true but Reason (R) is false.
