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

Options

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

Answer

B

Explanation

Angular velocity of particle P about point A,
`omega_(A)=(v)/(r_(AB))=(v)/(2r)`
Angular velocity of particle P about point C,
`omega_(C)=(v)/(r_(BC))=(v)/(r )`
Ratio`(omega_(A))/(omega_(C))=((v)/(2r))/((v)/(r))=(1)/(2)`
