A particle is moving with constant speed in a circle as shown in (Fig. 5.163). Find the angular velocity of the particle A with respect to fixed point `B and C` if angular velocity with respect to `O is omega`.
.

Explanation

Angular velocity of `A` with respect to `O` is
`omega_(A C) = ((v_(A O))_|_)/(r_(A O)) = (v)/( r)= omega`
`:. omega_(A B) = ((v_(A B))_|_)/(r_(A B))= (v)/(2 r)=(omega)/(2)`
and `omega_(A C) = ((v_(A C))_|_)/(r_(A C)) = (v)/(3 r) = (omega)/(3)`.
