Physics Laws of Motion MHT CET 2022

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

(A) perpendicular to the plane of the circle
(B) along the tangent to the circle
(C) along the radius towards the centre of the circle
(D)zeroCorrect

Answer: (D)

Solution

In uniform circular motion (U.C.M.) the angular velocity is constant in magnitude and direction (perpendicular to the plane), so the angular acceleration , option (D). The quantity is the magnitude of the linear
