Four point charges are positioned at the corners of a square with side length 0.521 m. Charges q1 and q4 (located at top left and bottom left corner, respectively) are positive and charges q2 and q3 (located at top right corner and bottom right corner, respectively) are negative. All four charges have the same magnitude of 3.88 nC. What is the magnitude of the net electric field at point P, located at the midpoint of the left side?
I know the answer is 184 N/C but I am unsure how to approach the problem in order to solve it. Please help.

Four point charges are positioned at the corners of a square with a side length of 0.551 m. Charges q1 (located at top left corner) and q4 (located at bottom left corner) are positive and charges q2 (located at top right corner) and q3 (located at bottom right corner) are negative. All four charges have the same magnitude of 4.68 uC. How much work is required to bring another charge of q'= 5.05 uC from infinitely far away to point...
