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`
`:.(omega_(1))/(omega_(2))=(v//2r)/(v//r)=1:2`
