Question

A is directed vertically downward and b directed along north what is b x a

Answer 1

The vector or cross product A x B is defined as a vector, that is perpendicular to both A and B, with a direction given by the right hand rule or screw rule.

The direction of the cross product mat be found using right hand rule,

Point index finger in the direction the first vector A

Point middle finger in the direction of the second vector B

Thumb will point in the direction of the cross product C

Therefore, in the given data, the product A x B will be along west

Answer 2

The vector or cross product A x B is defined as a vector, that is perpendicular to both A and B, with a direction given by the right hand rule or screw rule.
