A body moves in a uniform circular motion,
A body moves in a uniform circular motion,
The correct option is C The body has an acceleration
Uniform circular motion definition:
An object is said to be in a uniform circular motion, if and only if that object travels in a circular path with constant speed at an instant of time.
Explanation for correct option
c) When a particle moves in a uniform circular motion, then that particle acquires acceleration.
Thus, the body will have some acceleration
Explanation for incorrect options
a) A particle executing uniform circular motion is constantly accelerating.
so acceleration is not equal to Zero.
b) In uniform circular motion the direction of motion keeps on changing as the particle moves in a circular path.
As the particle takes a number of rotations the displacement from the initial point to the final point also changes.
The velocity of the particle also changes because of the change in displacement.
So, The body does not move at constant velocity in a uniform circular motion.
Hence, option ( c) is correct.
