A projectile of mass 1 kg1 \mathrm{~kg} is projected with a speed of 10 m/s10 \mathrm{~m} / \mathrm{s} at an angle of 60∘60^{\circ} from the horizontal when projectile is at its highest point, its magnitude of angular momentum (about point of projection)
View answer and explanation
Correct option: B
754Nm/s\frac{75}{4} \mathrm{Nm} / \mathrm{s}
Option B (754Nm/s\frac{75}{4} \mathrm{Nm} / \mathrm{s}) is correct because it is calculated by finding the angular momentum at the highest point using the horizontal velocity and maximum height.
