wo protons, A and B, are next to an infinite plane of positive charge. Proton B is twice as far from the plane as proton A. Which proton has the larger acceleration? Neglect interactions between the protons. Two protons, A and B, are next to an infinite plane of positive charge. Proton B is twice as far from the plane as proton A. Which proton has the larger acceleration? Neglect interactions between the protons. Proton B. Proton A. Both have the same acceleration.
