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!
I'm guessing these formulas
C=Q/V = ε0 * A/d
V = E*d
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?
