At any instant,`overset rarr(F) = (4.0 hatj)N` acts on a `0.25kg` object that has position vector `overset rarr(r ) = (2.0hati - 2.0 hatk)m` and velocity `overset rarr(upsilon) = (-5.0 hati + 5.0 hatk) m//s`. About the origin, what are angular momentum and torque acting on the object ?

A

0

B

`1kgm^-2//s`

C

`4kgm^-2//s`
