A vector `vecA` points vertically upward and `vecB` points towards north. The vector produce `vecAxxvecB` is

A

zero

B

along west

C

along east

D

vectically downward

Text Solution

Verified by Experts

The correct Answer is:
B
Direction of vector A is along z-axis `becausevecA=ahatk`
Direction of vector B is towards north `becausevecB=bhatj`
Now `vecAxxvecB=ahatkxxbhatj=ab(-hatj)`
The direction is `vecAxxvecB` is along west.
