A body is projected from point A on an inclined plane having inclination θ with horizontal with velocity u in a direction perpendicular to the inclined plane as shown in figure. Then range of the projectile on inclined plane is

 

• A

  $\frac{2{\mathrm{u}}^2}{\mathrm{g}}\mathrm{tan\theta }.\mathrm{sec\theta }$

• B

  $\frac{{\mathrm{u}}^2}{\mathrm{g}}\sin 2\mathrm{\theta }.\mathrm{cos\theta }$

• C

  $\frac{2{\mathrm{u}}^2}{\mathrm{g}}\mathrm{sec\theta }$

• D

  $\frac{{\mathrm{u}}^2}{\mathrm{g}}\mathrm{sin\theta }$
