A particle of mass \( m \) is projected with a velocity \( v \)
\( \mathrm{P} \)
making an angle of \( 45^{\circ} \) with the horizontal. The
W
magnitude of the angular momentum of the projectile about the point of projection when the particle is at its maximum height \( h \) is
(1) zero
(2) \( \frac{m v^{3}}{4 \sqrt{2} g} \)
(3) \( \frac{m v^{3}}{\sqrt{2} g} \)
(4) \( m \sqrt{2 g h^{3}} \)
