A cylinder is released from rest from the top of an incline of inclination $\mathrm{\theta }$ and length ‘l’. If the cylinder roles without slipping, its speed at the bottom

• A

  $\sqrt{\frac{4\mathrm{glsin}\mathrm{\theta }}{3}}$

• B

  $\sqrt{\frac{3\mathrm{glsin}\mathrm{\theta }}{2}}$

• C

  $\sqrt{\frac{4\mathrm{gl}}{3\sin \mathrm{\theta }}}$

• D

  $\sqrt{\frac{4\mathrm{gsin}\mathrm{\theta }}{3\mathrm{l}}}$
