The position of a particle is given by `vecr=(hati+2hatj-hatk)` and momentum `vecp=(3hati+4hatj-2hatk)`. The angular momentum is perpendicular to theA. `x`-axisB. `y`-axisC. `z`-axisD. line at equal angles to all the three axes |
Answer» `vecl=vecrxxvecp=|[hati,hatj,hatk],[1,2,-1],[3,4,-2]|=-hatj-2hatk` | |
