A +3.0-nC charge Q is initially at rest a distance of 10 cm ( r1 ) from a +5.0-nC charge q fixed at the origin. Naturally, the Coulomb force accelerates Q away from q, eventually reaching 15 cm ( r2 ). The charge Q is repelled by q, thus having work done on it and losing potential energy. What is the work done by the electric field between r1 and r2 ? What is the change in the potential energy...
