Q1) an electron moving with the velocity of 5x 10( raised to the power 4) m/s enters into uniform electric field and acquires a uniform acceleration of 10 ( raised to the power 4) m/s ( raised to the power 2)in the direction of its initial velocity.

CALCULATE (1) time in which the electron would acquire a velocity double of it's initial velocity.

2) how much distance would electron cover in this time.

Q2) distance in covered (in cm)

time object a object b object c

1st 20 20 20

2nd 20 36 60

3rd 20 24 100

4th 20 30 140

5th 20 48 180

answer the following

Q1) which object is moving with constant speed and why?

Q2) which object is moving with constant acceleration ? how much is acceleration?

Q3) which object is moving with an irregular acceleration?

Q4) How much distance does a,b,c, cover in 5 seconds.
