Question

- 14. For vectors A and vector B, making an angle e, which one of the following
relation is correct?
Mark only one oval.
ĀXB = BXĀ
ĀXB= |AB| sin
Option 1
Option 2
ĀXB = |AB| cose

Answer 1

Answer:

If θ be the angle between two vectors

A

and

B

, the cross product will be

A

×

B

=AB

n

^

sinθ and dot product will be

A

.

B

=ABcosθ where

n

^

is the normal vector to

A

and

B

The one of the property of cross product is anti-commutative, i.e.

A

×

B

=−

B

×

A
