A vector vec(A) points verically upward ...

A vector `vec(A)` points verically upward and `vec(B)` points towards north. The vector product `vec(A) xx vec(B)` is

A

Zero

B

Along west

C

Along east

D

Vertically downward

Text Solution

Verified by Experts

The correct Answer is:
B
`vec(A) = A hat(k)` (Vertically upward out of plane)
`vec(B)= B hat(j)`
`vec(A) xx vec(B) = (A hat(k) xx B hat(j))= AB (- hat(i))`
