Three positive point charges are located at the corners of a rectangle as illustrated in the figure below. Find the electric field (in N/C) at the fourth corner if the charges are 91 nC, 2 nC, and 93 nC. The distances are d1 = 1 m and d2 = 0.2 m. (Let the positive X-direction be to the right, and the positive Y-direction be upward.)
