Three identical pt charges A,B,C are the vertices of a triangle. 'A' exerts force F on B.?

Question

An equal force F is exerted by C on B (angle ABC = 90 degrees). What is the net force on B???

Answer 1

Magnitude of net force would be sqrt(2) times magnitude of F and it will act along a line bisecting the angle between AB and CB produced. [ By Parallelogram law of forces]
