Question

Three equal point charges, each with charge 1.45?C , are placed at the vertices of an equilateral triangle whose sides are of length 0.650m . What is the electric potential energy U of the system? (Take as zero the potential energy of the three charges when they are infinitely far apart.)

Explanation / Answer

potential energy = 3*q^2 / (4pi*epsilon*length)
