Question:
The escape velocity of a satellite from the surface of earth does NOT depend on
The escape velocity of a satellite from the surface of earth does NOT depend on
Show Hint
Whether it's a pebble or a plane, the speed required to leave Earth is the same: $\approx 11.2 \text{ km/s}$.

- mass of the earth.
- mass of the object to be projected.
- radius of the earth.
- gravitational constant.
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
Escape velocity is $v_e = \sqrt{\frac{2GM}{R}}$.
Step 2: Meaning
$G$ is the gravitational constant, $M$ is the mass of Earth, and $R$ is the radius of Earth.
Step 3: Analysis
Looking at the formula, $v_e$ involves the parameters of the planet (Earth), but there is no term for the mass of the projectile/satellite ($m$).
Step 4: Conclusion
Thus, escape velocity is independent of the mass of the object being projected. Final Answer: (B)
