Question

An electron moving with the velocity of 5 x10^4 m/s enters into an uniform electric field and acquires a uniform acceleration of 10^4m/s in the direction of initial motion

1). Calculate the time in which the electron would acquire a velocity in its Initial velocity

2). How much distance the electron would cover in this time

1). Calculate the time in which the electron would acquire a velocity in its Initial velocity

2). How much distance the electron would cover in this time


ANSWER:- first of all we can write some given information

U=5X10^4

a=10^4

1). V=u+at

2u=u+at
=> t=v/a
5x10^4/10^4
By cutting both 10^4 we get the answer => 5

2). S= U+1/2at

=375,000m
