Q. A uniform disc of mass 2 kg and radius 15 cm is revolving around the central axis by 4 ${rads}^{- 1}$. The linear momentum of disc will be
A) $1.2\ kg - {ms}^{- 1}\ $
B) $1.0\ kg - {ms}^{- 1}$
C) $0.6\ kg - {ms}^{- 1}$
D) None of these
Explanation
(d) Since, in the given cause $v_{CM}$ is zero, so its linear momentum will also be zero.
