The escape velocity from the surface of earth of mass 'M' and radius 'R' is 'Ve'. The escape velocity from the surface of a planet whose mass and radius are 3 times that of the earth, will be

Options

  1. Aq V _ e
  2. B3 Ve
  3. CV e
  4. D12 Ve

Correct answer

C. V e

Step-by-step solution

V _ e = 2 GM R V _ e ^ = 2 G 3 M 3 R = 2 GM R = V _ e
