A point charge with charge q1 = 3.90 C is held stationary at the origin. A second point charge with charge q2 = -5.00 C moves from the point (0.170m , 0) to the point (0.230m , 0.255m). How much work is done by the electrostatic force on the moving point charge? Express your answer in joules. A point charge with charge q1 = 3.90 C is held stationary at the origin.
