Question

A vector A points vertically upward and B points towards north. The vector product AxB is
[a] Zero
[b] Along west
[C] Along east
[d] Vertically downward​

Answer 1

Explanation:

Correct option is B)

Here z -axis is vertically upward means normal to plane of paper as shown in figure. 

Thus, A=Ak^ and B=Bj^

So, A×B=Ak^×Bj^=−ABi^ 

Thus, it is along negative x-axis means along west.
