Three balls, with charges of +q, -2q, and +3q, are placed at the corners of a square measuring L on each side, as shown in the figure. The value of q is 1.80 10-6 C, and L = 40.0 cm. Assume this set of three balls is not interacting with anything else in the universe, and assume that gravitational interactions are negligible. +9 L- -29 L +39 (a) What is the magnitude of the net electrostatic force on the ball of charge -2q? 1.15 N (b) What is the magnitude of the net electrostatic force on the ball of charge +3q?
