Circular MotionEasy
Question
A particle is acted upon by a force of constant magnitude which is always perpendicular to the velocity of the particle. The motion of the particle takes place in a plane. It follows that
Options
A.its velocity is constant
B.its acceleration is constant
C.its kinetic energy is constant
D.it moves in a circular path
Solution
The given case is of uniform circular motion, in which speed of kinetic energy remains constant. Direction of velocity and acceleration keep on changing although its magnitude remains constant.
∴ Correct option are (c) and (d).
∴ Correct option are (c) and (d).
