Homework Help: Electric potential energy of the two protons?

  1. Apr 16, 2012 #1
    1. The problem statement, all variables and given/known data

    The nucleus of a helium atom contains two protons. In a simple model of this nucleus, the protons are viewed as point particles separated by a distance of 1.0 fm (1.0 x 10^-15 m). What is the electric potential energy of the two protons?

    please do step by step.
