Two masses M₁ and M₂ connected by means of a string which is made to pass over light, smooth pulley are in equilibrium on a fixed smooth wedge as shown in figure. If $\mathrm{\theta }={60}^{\circ }$ and $\mathrm{\alpha }={30}^{\circ }$ ,then the ratio of M₁ to M₂ is

• A

  1 : 2

• B

  $2:\sqrt{3}$

• C

  $1:\sqrt{3}$

• D

  $\sqrt{3}:1$
