Question:medium

A meteor of mass 'm' having a speed 'v' at infinity reaches the surface of the earth with a speed of (\(v_e\) is escape speed from the earth's surface)

Show Hint

Conservation of energy is a powerful tool for orbital mechanics and celestial body motion problems. Remember that gravitational potential energy is taken to be zero at infinity. The escape velocity formula \( v_e = \sqrt{2GM/R} \) is fundamental and frequently used.

\( \sqrt{2}v_e \)
\( v_e \)
\( 2\sqrt{v^2+v_e^2} \)
\( \sqrt{v^2+v_e^2} \)

Show Solution

The Correct Option is D
