The mass of a planet is six time that of the earth. The radius of the planet is twice that of the earth. If the escape velocity from the earth is ' V _ e ', then the escape velocity from the planet is

Options

  1. A3 ~V _ e
  2. B2 ~V _ e
  3. CV _ e
  4. D5 ~V _ e

Correct answer

A. 3 ~V _ e

Step-by-step solution

aligned & V_e= 2 G M R ; V_p= 2 GM _p R_p & V_p V_e = M_p M R R_p = 6 1 2 = 3 & V_p= 3 V_e aligned
