A particle is moving in U.C.M. with speed V and radius R . The angular acceleration of the particle is

Options

  1. AV^2 R Perpendicular to the plane of the circle.
  2. BV^2 R along the tangent to the circle.
  3. CV^2 R along the radius towards the centre of the circle.
  4. Dzero.

Correct answer

D. zero.

Step-by-step solution

Concept-based. During uniform circular motion, the angular velocity is fixed therefore, the angular acceleration is zero.
