The escape velocity of a body from any planet whose mass is six times the mass of earth and radius is twice the radius of earth will be ( V _ e = . escape velocity of a body from the earth's surface)
Options
- A3 ~V _ e
- B2 ~V _ e
- C3 2 ~V _ e
- D2 2 ~V _ e
Correct answer
A. 3 ~V _ e
Step-by-step solution
(D) aligned V _ e &= 2 GM R V _ e ^ &= 2 G 6 M 2 R &= 2 GM R 3 &= 3 ~V _ e aligned
