Question

2.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
(A) its velocity is constant
(B) its acceleration is constant
(C) its kinetic energy is constant
(D) it moves in a straight.​

Answer 1

Answer:

C

Explanation:

it's kinetic energy is constant

When a force of constant magnitude which is always perpendicular to the velocity of the particle acts on a particle, the work done and hence change in kinetic energy is zero.
