A projectile is fired with velocity u making angle θ with the horizontal. What is the angular momentum of the projectile at the highest point about the starting point ? Given that mass of the projectile is m

• A

  $\frac{\mathrm{mcos}\mathrm{\theta }}{2\mathrm{g}}$

• B

  $\frac{{\mathrm{mu}}^3{\sin }^2\mathrm{\theta cos}\mathrm{\theta }}{4\mathrm{g}}$

• C

  $\frac{{\mathrm{mu}}^3{\cos }^2\mathrm{\theta }}{2\mathrm{g}}$

• D

  $\frac{{\mathrm{mu}}^3{\sin }^2\mathrm{\theta cos}\mathrm{\theta }}{2\mathrm{g}}$
