An electron moting with a velocity of `5xx10^(4)ms^(-1)` enters into a uniform electric field and acquires a uniform accleleration of `10^(4)ms^(-2)` in the direction of its inintial motion.
(i) Colculate the time in which the electron would acquire a velocity double of its initial velocity
(ii) How much distance the electron would cover in this time ?
