Answer 1

Answer:

its an example

Explanation:

Let θ be the angle between two vectors a & bbthen

The scalar product is given as

a.b=abcosθ=6√=6√3 .....(1)

The magnitude of Vector product is given as

a*b=absinθ=6......(2)

The magnitude of Vector product is given as

Dividing (2) by (1) as follows

absinθ/abcosθ=6√√3/6

tanθ=1/√√3

θ=tan inverse 1/√√3

θ=30∘
