The angle between the vectors \(\left(\hat{i} + \hat{j}\right)\) and \(\left(\hat{i} + \hat{k}\right)\) is
Text Solution
Verified by ExpertsThe correct answer is:
C
\((\hat{i} + \hat{j}) \cdot (\hat{j} + \hat{k}) = 0 + 1 + 0 + 0 = 1\)
\(\cos \theta = \frac{\vec{A} \cdot \vec{B}}{|\vec{A}| |\vec{B}|} = \frac{1}{\sqrt{2} \times \sqrt{2}} = \frac{1}{2}\) \ \ \(\theta = 60^\circ\)
