Correct answer
C
Step-by-step explanation
Let Me is mass of earth then mass of planet Mp = 10Me.
And let Re is radius of earth then radius of planet Rp =
Escape velocity of earth,
Escape velocity of planet,
And let Re is radius of earth then radius of planet Rp =
Escape velocity of earth,
Escape velocity of planet,
