The escape velocity from the earth gravitational field depends upon:earth's
Correct answer: C. radius of earth
- A. rotation of earth
- B. mass of body
- C. radius of earth
- D. mass of earth
Explanation
Escape velocity, Ve =√( 2GM/R) Acceleration due to gravity, g= GM/R², which is always constant. Plugging this value of g in the first equation: Ve= √2gR , where R is the radius of the earth . From the above equation, we see escape velocity is dependent upon is gravitational acceleration and radius of the earth so option C is correct.
