If vectors \(\vec{A}=\cos \omega t \hat{i}+\sin \omega t \hat{j}\) and \(\vec{B}=\cos \frac{\omega t}{2} \hat{i}+\sin \frac{\omega t}{2} \hat{j}\) are functions of time, then the value of t at which they are orthogonal to each other is:
- t = 0
- \(t=\frac{\pi}{4 \omega}\)
- \(t=\frac{\pi}{2 \omega}\)
- \(\frac{m}{16}=1\)
Answer
(C) t= 2
