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

Options

A. The acceleration of th particle is zero
B. The acceleration of th particle is bounded.
C. The acceleration of th particle is necessarly in the plane of motion.
D. The particle must be undergoing a uniform circular motion

Answer

C

Explanation

As given motion is two dimensional motion and given that insantaneous speed `v_(0)` is positive constant.Acceleration is rate of change of velocity (instanteous speed hence it will be in the plane of motion.
