Question

Statement I: Two projectiles having same range must have the same time of flight.
Statement II: Vertical component of velocity is constant in projectile motion under gravity

• A. Both statement I and II are correct.
• B. Both statement I and II are incorrect.
• C. Statement I is correct but statement II is incorrect.
• D. Statement II is correct but statement I is incorrect

Answer 1

Answer: (D)

Assertion-1 is false because angles of projection $\theta$ and $\left(90^{\circ }-\theta \right)$ give same range but time of flight will be different.
