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 electrical intensities are vectors and add vectorially.
