The escape velocity of body from a planet does not depend upon;
Correct answer: A. The mass of a body
- A. The mass of a body
- B. The mass of the planet
- C. The average radius of the planet
- D. The density of the planet
Explanation
The escape velocity 'v' of a body depends upon the acceleration due to gravity of the planet and the radius of the planet but not on mass of planet.

About Law of Universal Gravitation
Every two masses attract each other with a force proportional to the product of their masses and inversely proportional to the square of their separation, expressed as F = Gm₁m₂/r². Questions also involve the gravitational constant, vector direction, superposition of gravitational forces, and the distinction between gravitational force and gravitational field strength.
