SATHEE: Kinematics Question 706

Kinematics Question 706

Question: A particle $P$ is moving in a circle of radius $‘ a^{'}$ with a uniform speed $v$ . $C$ it’s the centre of the circle and $A B$ it’s a diameter. When passing through B the angular velocity of $P$ about $A$

and $C$ are in the ratio [NCERT 1982]

Options:

A) 1 : 1

B) 1 : 2

C) 2 : 1

D) 4 : 1

Show Answer

Answer:

Correct Answer: B

Solution:

Angular velocity of particle P about point A, $ω_{A} = \frac{v}{r_{A B}} = \frac{v}{2 r}$

Angular velocity of particle P about point C, $ω_{C} = \frac{v}{r_{B C}} = \frac{v}{r}$

Ratio $\frac{ω_{A}}{ω_{C}} = \frac{v / 2 r}{v / r} = \frac{1}{2} .$
