Question

A particle P is moving in a circle of radius ‘a’ with a uniform speed v. C is the centre of the circle and AB is a diameter. When passing through B the angular velocity of P about A and C are in the ratio

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

Answer 1

Answer: (B)

1 : 2

Answer 2

Angular velocity of P about A

$\omega_{A} = \frac{v}{2a}$

Angular velocity of P about C

$\omega_{C} = \frac{v}{a}$

∴ $\frac{\omega_{A}}{\omega_{C}} = 1:2$
