Question

Two balls of masses, M and 2M, are dropped from the top of a building at the same time. Which of the following statements is false for the given scenario?

• A. Both the balls hit the ground at the same time.
• B. The initial velocities of both the balls are zero.
• C. The final velocities of both the balls are equal.
• D. None of the above

Answer 1

The correct option is D None of the above

Both the balls have the same initial velocity (zero) and constant acceleration (g). By the second equation of motion,
$s=ut+\frac{1}{2}a{t}^2$, they will take the same time to cover equal displacements.

The final velocity of both the balls can be calculated by the equation, $v=u+at$. Since both the balls have equal initial velocities and equal acceleration, and take equal time to complete the journey, their final velocities will also be equal.
