Three charged particles of q1 = 70.0 nC, q2 = −70.0 nC, and q3 = 35.0 nC are placed on the y-axis, as shown in the figure. Charge q1 has the coordinates (0, 12.0 cm), q2 has the coordinates (0, −12.0 cm), and q3 is located at the origin. (a)Find the electric potential energy (in J) of the configuration of the three fixed charges. (b)A fourth particle, with a mass of 1.74×10−13 kg and a charge of q4 = 140.0 nC, is released from rest at the point (9.00 cm, 0). Find its speed (in m/s) after it has moved freely to a very large distance away.
