MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Three charged particles of q1 = 7'00 nC, dz = ?0.0 nC, and q3 = 35.0 nC are placed on the y-axis, as shown in the gure. CD Charge ql has the coordinates (0, 12.0 cm), qr2 has the coordinates (0, 12.0 cm), and (33 is located at the origin. (a) Find the electric potential energy (in J) of the configuration of the three fixed charges. k J (b) A fourth particle, with a mass of 1.50 x 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. I *im/s
