Problem

A point charge q1=+2.40 μCq_1=+2.40\,\mu\mathrm{C} is held stationary at the origin. A second point charge q2=−4.30 μCq_2=-4.30\,\mu\mathrm{C} moves from (x,y)=(0.150 m,0)(x,y)=(0.150\,\mathrm{m},0) to (x,y)=(0.250 m,0.250 m)(x,y)=(0.250\,\mathrm{m},0.250\,\mathrm{m}). How much work is done by the electric force on q2q_2?
