JEE Main 2024 — 27 January, Shift 1 — Question 36

Two bodies of mass 4 g and 25 g are moving with equal kinetic energies. The ratio of magnitude of their linear momentum is

  1. Option A:

    3:53: 5

  2. Option B:

    5:45: 4

  3. Option C:

    2:52: 5

    Correct
  4. Option D:

    4:54: 5

Answer: C

Step-by-step solution

P122 m1=P222 m2\frac{\mathrm{P}_{1}^{2}}{2 \mathrm{~m}_{1}}=\frac{\mathrm{P}_{2}^{2}}{2 \mathrm{~m}_{2}}

P1P2=m1 m2=25\frac{\mathrm{P}_{1}}{\mathrm{P}_{2}}=\sqrt{\frac{\mathrm{m}_{1}}{\mathrm{~m}_{2}}}=\frac{2}{5}
