1.

The position of the particle is given by `vec(r )=(vec(i)+2vec(j)-vec(k))` momentum `vec(P)= (3vec(i)+4vec(j)-2vec(k))`. The angular momentum is perpendicular toA. x-axisB. y-axisC. z-axisD. Line at equal angles to all the three axes

Answer» Correct Answer - A
`vec(L)= vec(r )xxvec(P)=| (hat(i),hat(j),hat(k)), (1,2,-1), (3,4,-2)|=-hat(j)-2hat(k)`
i.e., the angular momentum is perpendicular to x-axis.
