If $\theta$ is the angle between any two vectors $ \overrightarrow{a} and \overrightarrow{b} ,$ then $|\overrightarrow{a}.\overrightarrow{b} | = | \overrightarrow{a} \times \overrightarrow{b} | $ when $\theta$ is equal to

\[\begin {array} {1 1} (A)\;0 \quad (B)\;\frac{\pi}{4} \quad (C)\;\frac{\pi}{2} \quad (d)\;\pi \end {array}\]

Can you answer this question?

$\large\frac{\pi}{4}$ because $ab \cos \theta= ab \sin \theta$
Hence b is the correct answer.
