A particle of mass m is projected from point P on the ground with initial speed v at an angle θ with horizontal. Find the angular momentum of particle w.r.t. point P when it is at highest point of its trajectory.

• A

  $\frac{m{u}^3{\sin }^2\theta \cos \theta }{2g}$

• B

  $\frac{m{u}^3\cos \theta \sin \theta }{g}$

• C

  $\frac{m{u}^3\cos \theta {\sin }^2\theta }{g}$

• D

  $\frac{m{u}^3{\cos }^2\theta \sin \theta }{2g}$
