A point charge q1 = +2.10 uC is held stationary at the origin. A second point charge q2 = -4.60 uC moves from the point x=0.150 m, y=0 to the point x=0.250 m, y=0.270 m. How much work is done by the electric force on q2?

A point charge {\rm q}_1 = +2.40\mu {\rm{{\rm C}}} is heldstationary at the origin
