Chapter 21, Problem 82GP
Two pοint charges, Q1 = −6.7 μС and Q2 = 1.8 μC, are located between two oppositely charged parallel plates, as shown in Fig. 21–73. The two charges are separated by a distance of x = 0.34 m. Assume that the electric field produced by the charged plates is uniform and equal to E = 73,000 N/C. Calculate the net electro-static force on Q1 and give its direction.
