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

qEy

`qEye^2`

`q^2Ey`

`qE^2y`

Text Solution

Verified by Experts

The correct Answer is:

`W=qV =Delta K= k-0`
`qEy = K,` As E is uniform
`K= qEy`
