Escape Velocity

The escape velocity of a body depends upon mass as

Show answer and solution

Answer: (a)

  1. ve=2GMRv_e = \sqrt{\frac{2GM}{R}} contains only the planet's mass MM and radius RR.
  2. It does not depend on the body's mass mm, so ve∝m0v_e \propto m^{0}.
  3. So the answer is (a) m0m^{0}.
