The radius vector and linear momentum are respectively given by vector 

\mathrm{2\hat i} + 2\mathrm{\hat j} + \mathrm{\hat k \,\,and\,\, 2\hat i} - 2\mathrm{\hat j} + \mathrm{\hat k}

  Their angular momentum is

View answer and explanation

Correct option: B

4\mathrm{\hat i} - 8\mathrm{\hat k}

Option B (

4\mathrm{\hat i} - 8\mathrm{\hat k}

) is correct because the angular momentum is calculated using the cross product of the radius vector and linear momentum:

\vec{L} = \vec{r} \times \vec{p}
