Two identical point charges are fixed to diagonally opposite corners of a square that is .5m on a side. Each charge is 3.0E-6 C. How much work is done by the electric force as one of the charges moves to an empty corner?

Three point charges are fixed in place in a right triangle. What is the electric force on the q = -0.63 C charge due to the other two charges? (Let Q1 = +0.83 C and Q2 = +0.9 C.) what is the magnitude N, and direction in degrees above the positive x-axis?
