A particle of mass m is projected with a velocity v making an angle of 45° with the horizontal. The magnitude of angular momentum of the projectile about an axis of projection when the particle is at maximum height h is :
- zero
- \(\frac{m v^{3}}{4 \sqrt{2} g}\)
- \(\frac{m v^{2}}{\sqrt{2} g}\)
- \(m \sqrt{2 g h^{3}}\)
Answer
(B) m v^ 3 4 2 g
