Solution
The correct option is B West
Given the vector →P is vertically upward and the vector →Q directed north, the cross product of the vector can be calculated from the Right hand curl rule.
Curl your fingers from vertically upward(Z) direction to the north (Y) Direction.
The direction of the thumb gives the direction of the cross product, ie, −x axis.
Hence, west
→P = ^k
→Q=^j
→P×→Q=^k×^j=−^i
