Question

The angle between the vectors (A cross B) and (B cross A) is

Answer 1

Answer:

Anyway from this, we know that the A×B vector and B×A vector are equal in magnitude but in opposite direction, i.e they are antiparallel, so the angle between them is 180° or π rads. The angle between vectors a and b is 60 with |a|=2 and |b|=1.

Answer 2

Question :

The angle between the Vector ( A cross B ) and ( B cross A ) is

AnsWer :

π.

Formula :

$\blacksquare \tt \: \: Vector \times Vector \longrightarrow Vector. \\ \blacksquare \: \: \tt \vec{A} \times \vec{B} = |A| |B| \sin \theta \: \hat{n}$

Solution :

$\tt \vec{A} \times \vec{B} = |A| |B| \sin \theta \: \hat{n}.$

When, we move Vector A to B ñ, it's direction show upward.

And,

$\tt\vec{B} \times \vec{A} = |B| |A| ( \hat{ - n}).$

When, we move Vector B to A ñ, it's direction show downward.

The angle between A to B and B to A is Anti-parallel or 180°.

Therefore,the value of vector ( A to B ) and Vector (B to A ) is π.
