Find the electric potential energy for the following array of charges: charge q1 = +3.0 µC is located at (x, y) = (0.0, 0.0) m; charge q2 = +3.0 µC is located at (4.0, 3.0) m; and charge q3 = −1.0 µC is located at (0.0, 3.0) m.
A hydrogen atom has a single proton at its center and a single electron at a distance of approximately 0.0537 nm from the proton. What is the electric potential energy in joules?
