The potential dissimilarity between the plates of a capacitor is 170 V. Midway among the plates, a proton and an electron are released. The electron is released from rest. The proton is projected perpendicularly toward the negative plate by an initial speed. The proton strikes the negative plate at the same instant that the electron strikes the positive plate. Ignore the attraction among the two particles, and discover the initial speed of the proton. (Answer in m/s please)
