A particle is acted upon by a force of constant magnitude which is always perpendicular to the velocity of particle.The motion of particle takes place in horizontal plane.It follows : (a)Linear momentum is constant (b)Velocity is constant (c)It moves in a circular path (d) Particle moves in straight line

Its kinetic energy is constant

Since the particle is acted upon by a force of constant magnitude which is always perpendicular to the velocity of the particle, so work done by the force in the direction of the velocity is zero. So the magnitude of velocity will not change due to the force.

 Kinetic energy is KE=21mv2=constant.
Now mass and magnitude of velocity will always be constant in this given situation so the kinetic energy will also be constant.
