A particle of mass `80` units is moving with a uniform speed `v=4 sqrt 2` units in `XY` plane, along a line `y=x+5`. The magnitude of the angular momentum of the particle about the origin is
A. `1600` units
B. `160sqrt(2)` units
C. `152sqrt(2)` units
D. `16sqrt(2)` units
A. `1600` units
B. `160sqrt(2)` units
C. `152sqrt(2)` units
D. `16sqrt(2)` units
Correct Answer – A
`bar(L)=bar(r)xxbar(p)=m(bar(r)xxbar(v))`
