MCQ
Assertion (A): Two particle of different mass, projected with same velocit, the maximum height attained by both the particle will be same.
Reason (R): The maximum height of projectile is independent of patricle mass. is equal to maximum height attained by projectile.
  • A
    Both A and R are true and R is the correct explanation of A.
  • B
    Both A and R are true but R is not the correct explanation of A.
  • C
    A is true but R is false.
  • D
    A is false but R is true.

Answer

(a) Both A and R are true and R is the correct explanation of A .
Explanation: The maximum height to which a projectile rises above the point of projection is, $H=\frac{u^2 \sin ^2 \theta}{2 g}$, which is independent of mass.
