Part A A point charge with charge q1 = 3.10 uC is held stationary at the origin. A second point charge with charge q2 = -4.40 uC moves from the point ( 0.170 m , 0) to the point ( 0.290 m , 0.280 m ). How much work W is done by the electric force on the moving point charge? Express your answer in joules. Use k = 8.99x109 N . m2 /C2 for Coulomb's constant: K = ATE View Available Hint(s) IVO AEd ? W = - 0.527 Submit Previous Answers
