Home » Physics » Physics miscellaneous » Question

A particle is moving in a uniform circular motion with constant speed v along a circle of radius r. The acceleration-of the particle is

1. zero
2. V
  r
3. V
  r²
4. V²
  r

Correct Option: D

When a particle is moving in a uniform circular motion with constant speed and radius. the acceleration of the particle is given by v2/r. The particle will exhibit centripetal acceleration.

	V
	r²

	V²
	r
