Question

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

Answer 1

Answer:

Hii mate

Explanation:

✒The particle is released from rest, and so by the work-energy theorem, this work will be equal to , where is the velocity of the particle after moving through a distance of metres. , where is the charge producing the electric field.

✒ This of course assumes that the initial distance between the charges and is zero.
