A uniform electric field exists in the region between toe oppositely charged plane parallel plates. An electron is released from rest at the surface of the negatively charged plate and strikes the surface of the opposition plate 2 cm away from the first in an intercval of `1.5 xx 10^(-8)s` . Find (a) the electric intensity ,(b) the velocity of the electron when it strikes the second plate.

Answer

(a) `1000 V m^(-1)` (b) `2.67 xx 10^(6) m s^(-1) `
