Center of Mass question

2024 · 31 Jan · Shift 1 · Q66

JEE MainPhysicsCenter of MassMCQ+4 / −1
An artillery piece of mass M1M_1M1​ fires a shell of mass M2M_2M2​ horizontally. Instantaneously after the firing, the ratio of kinetic energy of the artillery and that of the shell is:
  1. A
    M1/(M1+M2)M_1 /\left(M_1+M_2\right)M1​/(M1​+M2​)
  2. B
    M2M1\frac{M_2}{M_1}M1​M2​​
  3. C
    M1M2\frac{M_1}{M_2}M2​M1​​
  4. D
    M2/(M1+M2)M_2 /\left(M_1+M_2\right)M2​/(M1​+M2​)
