A uniform E exist between two metal plates one negative and other positive. The plate length is l and the separation of the plates is d.
(i) An electron and a proton start from the negative plate and positive plane, respectively, and go the opposite plates. which one of them wins this race?
(ii) An electron and a proton start moving parallel to the plates towards the other end from the midpoint of the separation of plates at one end of the plates. Which of two will have greater deviation when they come out of the plates if they start with the
(a) same initial velocity
(b) same initial kinetic energy, and (c ) same initial momentum.

Answer

Electron `y_egty_p=y_p,y_elty_p`
