An electron and a proton are placed at a distance from a large charged parallel

Question

An electron and a proton are placed at a distance from a large charged parallel plate. The electron and proton are far enough from each other so that their interaction is negligible. Let Fe and Fp represent the magnitudes of forces made by the plate on the electron and proton. Which of the following statements is true? Fe Fp To compare Fe and Fp we must know the sign of the charge on the plate To compare Fe and Fp we must know the magnitude of the charge on the plate To compare Fe and Fp we must know the magnitude and sign of the charge on the plate To compare Fe and Fp we must know the distance between the plate and each charge

Explanation / Answer

Both the electron and proton are the same distance from the plate. Their charge is the same, but opposite; thus, the plate will exert the same force against each of them, but in the opposite direction. Since we are only interested in the magnitudes of the forces, B) is correct. The magnitudes are equal.
