Homework Help: Physics 212

Posted by Paula on Thursday, February 14, 2013 at 7:49pm.

Three equal point charges, each with charge 1.50\mu C , are placed at the vertices of an equilateral triangle whose sides are of length 0.300m . 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 epsilon_0 = 8.8510−12\frac{C^2}{N \cdot m^2} for the permittivity of free space.

how do I go about solving this problem? thank you very much for any guidance
