Two charges are placed on the x axis. One of the charges (q1 = +9.3 µC) is at x1 = +3.4 cm and the other (q2 = -20 µC) is at x2 = +8.9 cm.

(a) Find the net electric field (magnitude and direction) at x = 0 cm. (Use the sign of your answer to indicate the direction along the x-axis.)

(b) Find the net electric field (magnitude and direction) at x = +5.4 cm. (Use the sign of your answer to indicate the direction along the x-axis.)
