Part A

A point charge with charge $q_1=3\mathrm{.}10C$ is held statioflary at the origin. A second point charge with charge $q_2=-4\mathrm{.}50C$ moves from the point $(0\mathrm{.}155m,0)$ to the point $(0\mathrm{.}230m,0\mathrm{.}250m).$

How much work is done by the electrostatic force on the moving point charge?
