Question

Three charges each of +1microcoulomb are placed at the corners of an equilateral triangle.if the force between any two charges be F, then the net force on either charge will be

Arun · Accepted Answer

So, here all are the positive charges, then the forces due to two charges on the third acts away from respective charges. So, the angle between the two forces is 600. Then, according to the principle of superposition,
Fnet = sqrt ( F² + F² + 2 F² cos (pi/3))
Fnet = sqrt(3 F²)
Fnet = F * sqrt(3)
