AP EAMCET · PHYSICS · Center of Mass Momentum and Collision
A light body of momentum ' \(\mathrm{P}_{\mathrm{L}}\) ' and a heavy body of momentum ' \(\mathrm{P}_{\mathrm{H}}\) ', both have the same kinetic energy, then
- A \(\mathrm{P}_{\mathrm{L}} \gt \mathrm{P}_{\mathrm{H}}\)
- B \(\mathrm{P}_{\mathrm{H}} \gt \mathrm{P}_{\mathrm{L}}\)
- C \(P_L=P_H\)
- D Always \(\mathrm{P}_{\mathrm{H}}=2 \mathrm{P}_{\mathrm{L}}\)
Answer & Solution
Correct Answer
(B) \(\mathrm{P}_{\mathrm{H}} \gt \mathrm{P}_{\mathrm{L}}\)
Step-by-step Solution
Detailed explanation
\mathrm{K}_{\mathrm{H}}=\mathrm{K}_{\mathrm{L}} \Rightarrow \frac{\mathrm{P}_{\mathrm{H}}^2}{2 \mathrm{~m}_{\mathrm{H}}}=\frac{\mathrm{P}_{\mathrm{L}}^2}{2 \mathrm{~m}_{\mathrm{L}}} \Rightarrow…
