Answer to Question #121138 in Classical Mechanics for Lizwi

Question

If you change the sequence of the two vectors in the vector(cross) product, what will happen?
1 : The magnitude of the resultant vector will change and the direction will be opposite
2 : The magnitude of the resultant vector will change and the direction will be same
3 : The magnitude of the resultant vector will be same and the direction will be opposite
4 : The magnitude of the resultant vector will be same and the direction will be same

Answer 1

If we change the sequence of the two vectors in the vector(cross) product

The magnitude of the resultant vector will be same and the direction will be opposite
