Three point charges are shown in the figure. Two are located on the x-axis (both are a distance d from the origin). The third charge (Q, which is positive) is located distance L from the origin along the minus y-axis. The charge to the left has charge 3.4q0 and that on the right has charge q0 (both positive). What is the ratio of Q/q0 if the electric field at the origin makes an angle of 45 degrees with respect to the positive x-axis and the distance L = 1.8d? Your answer is a simple ratio expressed as a decimal number.
