Two charges q = +2.0μC are fixed a distance d = 2.0 cm apart (Figure).

(a) With V = 0 at infinity, what is the electric potential at point C?

(b) You bring a third charge q = + 2.0μC 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?
