Question

Select One Correct Option from the following: A smooth sphere A is moving on a frictionless horizontal plane with angular velocity $\omega$ and centre of mass velocity v. It collides elastically head on with an identical sphere B at rest. Neglect friction After the collision their angular speeds are $\omega_{A} \ and \ \omega_{B}$ respectively. Then,
(A)$\omega_{A} \ \textless \ \omega_{B}$
(B)$\omega_{A} = \omega_{B}$
(C)$\omega_{A}=\omega$
(D)$\omega_{B}=\omega$.

Answer 1

a option is correct I think

Answer 2

Select One Correct Option from the following: A smooth sphere A is moving on a frictionless horizontal plane with angular velocity $\omega$ and centre of mass velocity v. It collides elastically head on with an identical sphere B at rest. Neglect friction After the collision their angular speeds are $\omega_{A} \ and \ \omega_{B}$ respectively. Then,

✔️(A)$\omega_{A} \ \textless \ \omega_{B}$

(B)$\omega_{A} = \omega_{B}$

(C)$\omega_{A}=\omega$

(D)$\omega_{B}=\omega$.
