Question

Three particles having charges +q, +Q and -Q are placed at the corners of an equilateral triangle of sides a, as shown above.The net force on the particle with charge +q due to the other charges is in the plane of the screen and directed vertically upvertically downhorizontally to the righthorizontally to the leftToward the charge -Q_________________.

Answer 1

In the given figure,

The diagram shows the forces exerted by the charges +Q and -Q on the charge +q.

Thus, the net force on the particle with charge +q due to the other charges is in the plane of the screen and directed horizontally to the right.

Thus, the given option (c) is correct.
