The ratio between the values of cross product and dot product of two vectors is `1/sqrt(3)` . The angle between then is

Options

A. `30^@`
B. `45^@`
C. `60^@`
D. `120^@`

Answer

A

Explanation

For `vecA and vecB`
`("value of cross product")/("value of dot product")=(AB sin theta)/(AB cos theta)=tan theta`
`because tan theta =1/sqrt(3) =tan 30^@`
Hence the angle between the two vectors , `theta =30^@` .
