An insect of mass m=1 gm moves with a velocity `v= hat(i) - 2hat(j) + hat(k) m//s`. Find its angular momentum `vec(L)` about the origin O when the insect passes through the point P(-1, 1,2) m. Use `vec(L) = vec(r ) xx m vec(v)`

A

`(5 hat(i) + 3hat(j) + hat(k)) 10^(-3)`

B

`(3 hat(j) + hat(k))`

C

`(5 hat(i) - 3hat(j))`

D

null vector
