Which of the following relations is true for two unit vector \stackrel{\^}{A} and \stackrel{\^}{B} making an angle \theta to each other? [25-Jun-2022-Shift-1]

Correct Answer is : |∧A−∧B|=|∧A+∧B|tanθ2

|\hat{A}+\hat{B}|=|\hat{A}-\hat{B}| \tan \frac{\theta}{2}

|\hat{A}-\hat{B}|=|\hat{A}+\hat{B}| \tan \frac{\theta}{2}

|\hat{A}+\hat{B}|=|\hat{A}-\hat{B}| \cos \frac{\theta}{2}

|\hat{A}-\hat{B}|=|\hat{A}+\hat{B}| \cos \frac{\theta}{2}
