Question

Escape velocity when a body of mass \( m \) is thrown vertically from the surface of the earth is \( v \). What will be the escape velocity of another body of mass 4m thrown vertically?

• A. \( v \)
• B. \( 2v \)
• C. \( 4v \)
• D. None of these

Hint:

Escape velocity depends on the mass and radius of the planet, not on the mass of the object.

Answer 1

The Correct Option is A

Escape velocity is independent of the mass of the object being thrown. It only depends on the mass of the Earth and the distance from the center of the Earth. Therefore, the escape velocity for the second body is the same as for the first body.
Final Answer: \[ \boxed{v} \]
