Question

An electron moving with a velocity of 5×10^3 m/s enters into uniform electric field and acquires a uniform acceleration of 10^3 m/s^2 in direction of initial velocity. 1.Find out the time in which electron velocity will be doubled.? 2.How much distance electron would cover in this time.?​

Answer 1

Answer:

1. In the direction of its initial motion. Calculate the time in which the electron would acquire a velocity double of its initial velocity. Thus, the time in which electron acquire a velocity double of its initial velocity is 5 seconds.

2. Using s=ut+21​at2 =(5×104)×5+21​(104)×(5)2=25×104+225​×104=37. 5×104m.
