A point charge with charge q1 = 3.50 μc is held stationary at the origin. a second point charge with charge q2 = -4.10 μc moves from the point ( 0.160 m , 0) to the point ( 0.245 m , 0.240 m ). how

A point charge with charge q1 = 3.50 μc is held stationary at the origin. a second point charge with charge q2 = -4.10 μc moves from the point ( 0.160 m , 0) to the point ( 0.245 m , 0.240 m ). how much work w is done by the electric force on the moving point charge?
