A) \[14.4\,kg\,{{m}^{2}}{{s}^{-1}}\]
B) \[8.64\,kg\,{{m}^{2}}{{s}^{-1}}\]
C) \[20.16\,kg\,{{m}^{2}}{{s}^{-1}}\]
D) \[11.52\,kg\,{{m}^{2}}{{s}^{-1}}\]
Correct Answer: A
Solution :
[a] Angular momentum, \[{{L}_{0}}=mvr\,\sin \,{{90}^{o}}\] \[=2\times 0.6\times 12\times 1\times 1\] [\[As\,V=r\omega ,\,Sin\,{{90}^{o}}=1\]] \[So,\,\,{{L}_{0}}=14.4\,kg{{m}^{2}}/s\]You need to login to perform this action.
