A particle of mass m and charge q is placed at rest in a uniform electric field E and then released, the kinetic energy attained by the particle after moving a distance y will be

`q E y^(2)`

`q E ^(2)`

q E y

`q^(2) E y`

Text Solution

Verified by Experts

The correct Answer is:

K.E . Acquired = work done
= force `xx` distance ` = q E xx y = q E y`
