Hey!

I am having trouble understanding what this question is answering, and also how to go about answering it! Hopefully some help can be derived from this thread.

**Question **
Explain where the quantity

is a vector, scalar, or neither. Explain your answer.

**Solution **
I don't understand what this question is asking. I know how to tell if something is a scalar or vector quantity (for example the wind blowing at 20km/h is scalar, but the wind blowing at 20km/h going NW is a vector) but I don't know how to apply it to this question!

I also know how to calculate the cross and dot products.

Thanks for your help!
