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 eachother are equal thus giving no exerted force.
