Question

An electron moving with a velocity of 5X 10'm/s enters into a uniform electric field and acquires a uniform acceleration of 10 m/s.
a. Calculaic the time in which the electron would acquire a velocity double of its initial velocity.
b. How much distànce will be covered by the electron?

Answer 1

Answer:

Initial velocity of the electron is u =5×104 m/s

Acceleration of the electron is a=104 m/s2

From first equation of motion,

v=u+at

2u=u+at

t=u/a=(5×104)/(104)=5s

(C) 5
