Hey!(adsbygoogle = window.adsbygoogle || []).push({});

I need help for this problem.

The mass of a hypothetical planet is 1/100 that the Earth and its radius is 1/4 that of the Earth. If a person weigths 150 lb on the earth, what would he weigth on his planet?

I tried the formula g=GM/r^2 by doing a ratio but I do not find the right answer.

Thank you

B
