KE=0.5mv^2
since mass is constant and force as well as magnetic field does not change or put an effect on velocity oof particle therefore its velocity remains constant therefore kinetic energy remains constant

Hey !!
The force, experienced by the charged particle is perpendicular to the instantaneous velocity v(bar) at all instants. Here the magnetic force cannot bring any change in the speed of the charged particle. Since speed remains constant, the kinetic energy also stays constant.
Good luck !!
