Question

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 is

Answer 1

Answer:

Hii mate

Explanation:

A particle of mass m and charge q is placed at rest in a uniform electric field E and then released. ... A particle (mass m, charge q) is projected with velocity v inside a fixed smooth groove in the shape of a sine curve.

I hope it's helpful ❤✌❤

Answer 2

Answer:

KE=Eqy

Explanation:

Initially charged particle was at rest Initial kinetic energy Ki=0

After releasing charge particle , it attends velocity

Final Kinetic=Kf > 0

Therefore kinetic energy is changed

Now According to work energy theorem ∆K=W

Therefore Kf – Ki=Force x displacement

Kf– 0=F x y displacement is y given

=Eqy ( Force on the charge in electric field E=Eq
