Question

three equal and similar charges are placed at (-a 0 0) (0 0 0) (a 0 0). what is the nature of equilibrium of the charge at the origin

Open in App

Solution

Three equal and similar charges(+q) are placed at the points (-a,00) (0,0,0) and (a,0,0) respectively. Total magnitude of charge at the origin = +q+q+q = 3q. the nature of the charge is repulsive in nature as like charges repel each other.
