Your Ultimate Guide to JEE & NEET Question Solutions

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 line

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

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