A) 7.5 unit
B) 60 unit
C) \[40\sqrt{2}\]unit
D) zero
Correct Answer: B
Solution :
Angular momentum, \[J=mvr\] where, r is length of perpendicular drawn on line\[y=x+4\]from origin \[=\frac{0-0+4}{\sqrt{{{1}^{2}}+{{1}^{2}}}}=\frac{4}{\sqrt{2}}\] \[\therefore \] \[J=5\times 3\sqrt{2}\frac{4}{\sqrt{2}}=60\,unit\]You need to login to perform this action.
