A particle P is moving in a circle of radius r with a uniform speed u. C is the centre of the circle and AB is diameter. The angular velocity of P about A and V are in the ratio :

Options

A. `1:1`
B. `1:2`
C. `2:1`
D. `4:1`

Answer

B

Explanation

Angular velocity about `A, omega_1=v//2r`

Angular velocity about `C,omega_2=v//r`
`therefore" "omega_1//omega_2=(v//2r)//(v//r)=1//2`
