JEE MainPhysicsGravitationMCQ+4 / −1
The escape velocity of a body depends upon mass as
  1. A
    m0{m^0}m0
  2. B
    m1{m^1}m1
  3. C
    m2{m^2}m2

Correct answer: A

  1. Formula for escape velocity

    The escape velocity from the surface of a planet is ve=2GMRv_e = \sqrt{\frac{2GM}{R}}ve​=R2GM​​ where:

    • GGG = gravitational constant
    • MMM = mass of the planet
    • RRR = radius of the planet
  2. Dependence on the mass of the body

    In this formula, there is no dependence on the mass mmm of the escaping body.

    So, ve∝m0v_e \propto m^0ve​∝m0

  3. Check the options

    • A: m0m^0m0 ✅
    • B: m1m^1m1 ❌
    • C: m2m^2m2 ❌
    • D: m3m^3m3 ❌
  4. Conclusion

    The escape velocity is independent of the mass of the body.

    Hence, the correct answer is: A\boxed{A}A​
