A particle is acted upon by a force of constant
\( \mathrm{P} \)
magnitude which is always perpendicular to the velocity of the particle. The motion of the particle takes place in a plane. It follows that:
(1) its velocity is constant
(2) its acceleration is constant
(3) its kinetic energy is constant
(4) it moves in a circular path
