A particle of mass m is projected with velocity v at an angle q with the horizontal. Find its angular momentum about the point of projection when it is at
the highest point of its trajectory.

• A

  $\frac{{\mathrm{mv}}^2\mathrm{sin\theta sin}2\mathrm{\theta }}{4\mathrm{g}}$

• B

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

• C

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

• D

  None of these
