1. The problem statement, all variables and given/known data The parameters of an air-filled parallel plate capacitor are: d = 5mm and A = 500cm2. The charge of the electrodes are Q = 10nC and −Q. Inside of the capacitor in the middle point there is a point charge of 0, 02Q. Find the magnitude of the force acting to the point charge! 2. Relevant equations I'm guessing these formulas C=Q/V = ε0 * A/d V = E*d 3. The attempt at a solution The answer is supposed to be 4.52 * 10-6 N However I plug in the values and get 9.02 N.. Am I using the wrong formulas, or am I just calculating it wrong?
