MCQ
Two balls of different masses have the same $KE$. Then the:
  • Heavier ball has greater momentum than the lighter ball.
  • B
    Lighter Will has greater momentum than the heavier ball.
  • C
    Both bans have equal momentum.
  • D
    Both balls have zero momentum.

Answer

Correct option: A.
Heavier ball has greater momentum than the lighter ball.
The relation between kinetic energy $(K)$ and momentum $(p)$ is given by, $\text{K}=\frac{\text{p}^2}{2\text{m}}$
where $m$ be the mass of the body
So, $\text{p}=\sqrt{2\text{mk}}$
As kinetic energy is constant,
so $\text{p}\propto\sqrt{\text{m}}$
