Question

if magnitude of vector A× vector B =√3 vector a dot vector b , then the value of Magnitude a vector . b vector is​

Answer 1

Answer:

The value of angle between A and B is 60° or π/3 rad

Explanation:

Given that,

A×B = √3 A·B

We know that,

A·B = ABcosФ

A×B = ABsinФ

Putting these values in we get,

A×B = √3 A·B

ABsinФ = √3 ABcosФ

sinФ / cosФ = √3

tanФ = √3

Ф = 60° or π/3 rad
