enters into a uniform
electric field and acquires a uniform acceleration of
in the direction of its
initial motion.
(i) Calculate 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?
Answer:
Given, initial velocity, 
and acceleration, 
(i) According to the question, final velocity, v = 2u, t =
?
From first equation of motion, v = u + at
i.e., after 5 s electron will acquire a velocity double of
its initial velocity.
(ii) From second equation of motion,
Distance covered in t second,
