Which of the following relations is true for two unit vector $\displaystyle \hat{\mathrm{A}}$ and $\displaystyle \hat{\mathrm{B}}$ making an angle $\displaystyle \theta$ to each other ?
Official answer
(2)
$\displaystyle |\hat{\mathrm{A}}-\hat{\mathrm{B}}|=|\hat{\mathrm{A}}+\hat{\mathrm{B}}| \tan \frac{\theta}{2}$
