Q: In the rectangle in the drawing, a charge is to be placed at the empty corner to make the net force on the charge at corner A point along the vertical direction. What charge (magnitude and algebraic sign) must be placed at the empty corner? The picture shows a normal rectangle. The upper...

Well, I just found out you could plug this into a calculator and that it would work fine, and it does. I appreciate you taking the time to help me, though :).

I just need help with this force equation. I've plugged everything and I know the answer, I just can't get the steps right, and I want to know what I'm doing wrong. Equation: F = 8.99 X 10^9 X N X m^2/C^2 (4.8 X 10^-6C)^2 / (.50m)^2 Might be kinda hard for you guys to explain the...
