AIIMS 2019 Physics Maximum Height MCQ Question
A ball of mass is thrown up at an angle of to the horizontal at a speed of . The angular momentum of the ball at the highest point of the trajectory with respect to the point from which the ball is thrown is nearly
Correct Answer
Detailed Explanation
Option B is correct because it suggests substituting the expression for maximum height in the angular momentum formula, which is a valid approach to relate the concepts of projectile motion and angular momentum. The other options either misapply the formulas or provide incorrect calculations. For instance, option A correctly states the formula for maximum height, but it does not connect to angular momentum, while option C incorrectly combines the two concepts without proper derivation. Option D presents a numerical example that lacks context and does not follow the correct application of the formulas involved. Understanding the relationship between angular momentum (L = r × mv) and projectile motion is crucial for solving problems in mechanics.
