Two charges q = +2.0 μC are a fixed distance d = 2.0 cm apart (as in the figure). (a) With V = 0 at infinity, what is the electric potential at point C? A third charge q=+1.5 µC is brought from infinity to C. (b) What is the potential energy UE of the three charge configuration when the third charge is in place? (c) The third charge is then released from rest at point C while the other two charges remain fixed in place. If the mass of the third charge is 1.5 x 10-12 kg, then what is the speed of the third charge as it moves back out to infinity? C + 9 d/2 d/2d/2- 9
