The potential dissimilarity between the plates of a capacitor is 220 V. Midway between the plates; an electron and a proton are released. The electron is released from rest. The proton is projected perpendicularly toward the negative plate with 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)
If the ball's speed just before impact is 100 m/s, what is the angular speed of the rod immediately after the collision.
