Two simple harmonic motions are given by $x_{1} = a \sin \omega t + a \cos \omega t$ and $x_{2} = a \sin \omega t + \frac{a}{\sqrt{3}} \cos \omega t$. The ratio of the amplitudes of the first and second motion and the phase difference between them are respectively:

  • A
    $\sqrt{\frac{3}{2}}$ and $\frac{\pi}{12}$
  • B
    $\frac{\sqrt{3}}{2}$ and $\frac{\pi}{12}$
  • C
    $\frac{2}{\sqrt{3}}$ and $\frac{\pi}{12}$
  • D
    $\sqrt{\frac{3}{2}}$ and $\frac{\pi}{6}$
