Four charges located at the four corners of a rectangle as shown in the figure. The net electrostatic force on both q; and q, is zero 9₁=Q 3 cm 9₂ 4 cm 9₂=Q - What is Q/q₂ and Q/q₁? - If |Q| = 20 nC, what is the magnitude of the net electric field at the center of the rectangle? - If |Q| = 20 nC, what is the net potential at the center of the rectangle? (you should have two answers)
