The figure below shows two pint charges, each of -2Q, fixed on the y-axis at y = +a and at y = -a . A third
points charge -Q is placed on the x-axis at x = 2a . Express all algebraic answers in terms of Q, a, and
fundamental constants.
(a) What is the net force (magnitude and direction) on a charge -Q due to the other two charges? (7 points)
(b) What is the net electric field at the origin due to all three charges? (7 points)
(c) What is the electrical potential at the origin due to all three charges? (6 points)
