Question

a charged particle of mass m and charge q is released from rest in an electric field of uniform strength E . The kinetic energy of particle after time t is

Answer 1

Dear user.

force=qE,impulse=qEt=momentum=p, k.e.=p2/2m
Or

1) qE + mg = ma
a = qE/m + g

2) v = 0 + at

    v = (qE/m + g)t

 

3) K.E =1/2mv^2

        = 1/2m [(qE/m + g)t]^2 Joule

Hope it will help u
