1. The problem statement, all variables and given/known data[/b](adsbygoogle = window.adsbygoogle || []).push({});

At a distance H abouve the suface of a planet, the true weight of a remote probe is one percent less than its true wieght on the surface. The radius of the planet is R. Find the ration H/R.

2. Relevant equations[/b]

W=mg=G*(M(of planet)/r(squared))*M(of probe)

where G is the universal gravitational constant= 6.673x10-11 N*m2/kg2

r is the distance between the middle of the planet and the probe

3. The attempt at a solution[/b]

I tried to equate two equations, one for the weight on the probe on the surface, and one for the mass of the probe on H above the surface of the planet. I then tried to solve for H. That however didn't work at all as the provided answer is H/R= 0.005

Any help!!!???
