1. The problem statement, all variables and given/known data four charges aranged on the corners of a square. a fifth charge is located in the middle of the square. what is the net charge on that charge? givens: two charges -5uC are placed at opposite corners of the square, two charges 2uC are placed at opposite corners of the square, and the fifth charge is -1uC placed at the middle of the square 2. Relevant equations F=K(q1*q2)/r^2 3. The attempt at a solution i do not know if i can find a distance to use the coulombs law equation. the answer that i want to say is that there is no force exerted on the fifth charge because the charges at the corners opposite from eachother are equal thus giving no exerted force.
