Apoint charge with charge q1 = 3.10 μc is held stationary at the origin. a second point charge with charge q2 = -4.50 μc moves from the point ( 0.140 m , 0) to the point ( 0.265 m , 0.265 m ). how much work w is done by the electric force on the moving point charge?

To do work, this truck uses energy stored in chemical fuel and an electrical battery. how much total energy does this truck put out?
