Two charges q = +5.4 μC are fixed a distance d = 2.4 cm apart (see the figure). (a) With V = 0 at infinity, what is the electric potential at point C? (b) You bring a third charge q = +5.4 µC from infinity to C. How much work must you do? (c) What is the potential energy U of the three-charge configuration when the third charge is in place? (a) Number i Units + 1/2 9 (b) Number i Units (c) Number i Units d/2
