Suppose a charge of -1.60 µC is at the origin and a charge of 3.30 µC is at the point (0, 3.00) m.
(a) Find the electric potential at (4.00, 0) m, assuming the electric potential is zero at infinity. V = 3 . V What is electric potential? What factors affect the size of the electric potential at a particular point?
(b) Find the work necessary to bring a 3.70 µC charge from infinity to the point (4.00, 0) m. W = 4 . J How does the work done on an object relate to its change in electric potential? If necessary, go back and review the conservation of energy relationships.
