Consider two charges +q and -q placed at B and C of an equilateral triangle ABC. For this system, the total charge is zero. But the electric field (intensity) at A which is equidistant from B and C is not zero. Why?

Text Solution

Verified by Experts

Charges are scalars, but the electric intensities are vectors and can be added vectorially. Hence electric intensity is not equal to zero but its is .E..
