Question

two vectors A and B are directed along y axis and Z Axis respectively what is the direction of the vector B Cross A​

Answer 1

Answer: negative x axis

Explanation:

As A and B are directed along y axis and z axis respectively, therefore they are mutually perpendicular to each other.

Cross product of two vectors gives the vector perpendicular to both the vectors, therefore if A and B are perpendicular to each other, then their resultant cross product will be perpendicular to the y-z plane, which is the x axis.

A x B = A B sin ∅ in x axis

but B x A = A B sin ∅ in  - x axis
