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
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 each other are equal thus giving no exerted force.
