Three charged particles of q, = 30.0 nC, q, = -30.0 nC, and q; = 15.0 nC are placed on the y-axis, as shown in the figure. + 93 + X 92 Charge q, has the coordinates (0, 8.00 cm), q2 has the coordinates (0, -8.00 cm), and q; is located at the origin. (a) Find the electric potential energy (in ]) of the configuration of the three fixed charges. (b) A fourth particle, with a mass of 2.25 x 10 15 kg and a charge of q = 60.0 nC, is released from rest at the point (6.00 cm, 0). Find its speed (in m/s) after it has moved freely to a very large distance away. m/s Need Help? Read It
