Compare the binding energy of a body at rest on the surface of the earth with the binding energy of a body of same mass at rest on the surface of the moon. (g = 9.8 m/s^2 , Radius of the earth = 6400 km, Radius of the moon= 1747 km)

Question

Pooja · Answer

Binding energy on surface of earth is E e = GM e m/R e = mg e R e Similarly on moon it is E m = GM m m/R m = mg m R m Comparing both E e /E m = g e R e /g m R m = 9.8 × 6400 / 1.625 × 1747 =22 It is 22 time more on earth than on moon
