Electric potential energy:
Initial electric potential energy:
A point charge with a charge q1 = 3.10 μC is held stationary at the origin. A second point charge with a charge q2 = -4.10 μC moves from the point x = 0.130 m , y = 0 to the point x = 0.230 m , y = 0.290 m.
How much work is done by the electric force on q2?
