Problem
Three identical point charges q are placed at the vertices of an equilateral triangle of side a in air. The magnitude of the net force experienced by any one charge due to the other two is F.
Show that if every charge is simultaneously doubled to 2q while their positions remain unchanged, the net force on any one charge becomes 4F.
