Question

Three equal point charges, each with charge 1.25 μC , are placed at the vertices of an equilateral triangle whose sides are of length 0.450 m . 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.)

Use ϵ0 = 8.85×10⁻¹² C2N⋅m2 for the permittivity of free space.
