Question

A particle is revolving in a circle of radius r and centre at 'O' with uniform angular velocity . Choose the correct option(s) :

(A) the ratio of angular velocity at A about O and about B is 3 : 2. 

(B) the angular velocity at A about all points O,B and C is same. 

(C) the angular velocity at A about C is ω/2. 

(D) the velocity at A and C are same.

Answer 1

Correct option (A) (C)

Explanation:

Note: Construct a circle of that radius from the given point about which the angular velocity is to be detected.
