**Elena**, Wednesday, May 16, 2012 at 5:59amThe weight of an object is the force on the object due to gravity. It is the product of the mass m of the object and the magnitude of the local gravitational acceleration g (depends on the distance from the center of the Earth R)

If g→0 (at R →∞) weight →0 (weightlessness)

G•m•M(Earth)/x² = G•m•M(Mars)/(d-x)².

where d is the distance between thwe centers of the Earth and Mars.

M(Earth)/x² = M(Mars)/(d-x)².

Solving for x we can find the distance from the center of the Earth where the atractions “lander- Earth” and “lander-Mars” are equal.

Mass doesn’t change.
