In a two dimensional motion,instantaneous speed `v_(0)` is a positive constant.Then which of the following are necessarily true?

A

The acceleration of the particle is zero

B

The acceleration of the particle is bounded

C

The acceleration of the particle is necessarily in the plane of motion

D

The particle must be undergoing a uniform circular motion.

Text Solution

Verified by Experts

The correct Answer is:
C
As given motion is two dimensional motion and given that instantaneous speed `v_(0)` is positive constant. Acceleration is rate of change of velocity (instantaneous speed) hence it will also be in the plane of motion.
