1. Two charges are placed between the plates of a parallel plate capacitor. One charge is +q1 and the other is q2 = +4.66mC (microC). The charge per unit area on each plate has a magnitude of sigma = 1.27×10-4C/m2. The force on q1 due to q2 equals the force on q1 due to the electric field of the parallel plate capacitor. What is the distance r between the two charges?

2. Two identical small insulating balls are suspended by separate 0.258m threads that are attached to a common point on the ceiling. Each ball has a mass of 7.87×10-4kg. Initially the balls are uncharged and hang straight down. They are then given identical positive charges and, as a result, spread apart with an angle of 32.2o between the threads. Determine the charge on each ball.

Two identical small insulating balls are suspended by separate 0.291m threads that are attached to a common point on the ceiling. Each ball has a mass of 7.90×10-4kg. Initially the balls are uncharged and hang straight down. They are then given identical positive charges and, as a result, spread apart with an angle of 35.0o between the threads. Determine the charge on each ball. This is my third time posting this question :(
