Assertion: The angle between the two vectors

(\hat{i}+\hat{j})

and

(\hat{i}+\hat{k})

\frac{\pi}{3}

radian.
Reason: Angle between two vectors

\vec{A}

and

\vec{B}

is given by

\theta=\cos ^{-1}\left(\frac{\vec{A} \cdot \vec{B}}{A B}\right)

View answer and explanation

Correct option: A

If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion

Option A (If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion) is correct because the angle between the vectors can be calculated using the formula provided in the Reason, and the calculated angle matches the assertion.
