Solution

The correct option is B along west
Direction of vector $\to A$ is along $z$ -axis $\to A = a^k$
Direction of vector $\to B$ is towards north $\to B = b^j$
Now $\to A \times \to B = a^k \times b^j = a b (-^i)$
Hence the direction of $\to A \times \to B$ is along west.

A vector →A points vertically upward and →B point towards north. The vector product →A×→B is

The correct option is B along west Direction of vector →A is along z-axis →A=a^k Direction of vector →B is towards north →B=b^j Now →A×→B=a^k×b^j=ab(−^i) Hence the direction of →A×→B is along west.

A vector $\to A$ points vertically upward and $\to B$ point towards north. The vector product $\to A \times \to B$ is

The correct option is B along west
Direction of vector $\to A$ is along $z$ -axis $\to A = a^k$
Direction of vector $\to B$ is towards north $\to B = b^j$
Now $\to A \times \to B = a^k \times b^j = a b (-^i)$
Hence the direction of $\to A \times \to B$ is along west.
