A particle of mass $m$ is projected with a velocity ' $u$ ' making an angle of $3 0^{\circ}$ with the horizontal. The magnitude of angular momentum of the projectile about the point of projection when the particle is at its maximum height $h$ is:

Options:

Answer:

Solution:

Angular momentum, $L = m v H = m u cos 30 H$ $= m u cos 3 0^{\circ} \times \frac{u ^{2} s i n ^{2} θ}{2 g} [∵ H = \frac{u ^{2} s i n ^{2} θ}{2 g}]$ $= \frac{m u ^{3}}{2 g} \times \frac{3}{2} \times (\frac{1}{2})^{2} = \frac{3 m u ^{3}}{16 g}$
