A) 0 units
B) 30 units
C) 60 units
D) None of these
Correct Answer: C
Solution :
Angular momentum about origin is. \[r=\frac{\left| 0-0-4 \right|}{\sqrt{{{(1)}^{2}}+{{(-1)}^{2}}}}=2\sqrt{2}\] \[\left| L \right|=\left| r\times mv \right|\,=\,\,rmv\] \[=\left( 2\sqrt{2} \right)\times 5\times \left( 3\sqrt{2} \right)=60\,\,units\]You need to login to perform this action.
