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

from earth to mars, determine at what distance (from earth) the gravitation force of the earth acting on the space probe ( mass 200kg) is equal to the gravitational force of Mars on the space probe, if the planets are aligned.

Mass of earth: 5.976 x 10 ^ 24 kg

Mass of Mars: 6.394 x 10 ^ 23 kg

Mass of probe: 200kg

Radius of Mars: 3394 km

Radius of Earth: 6371 km

distance between Earth and Mars: 7.83 x 10 ^7 km

gravitational constant: 6.673 x 10 ^ -11

surface gravitational acceleeration of mars: 3.73 m/s^2

" "of Earth: 9.81 m/s^2

2. Relevant equations

F= Gmm / r^2

F=mg

3. The attempt at a solution

I'm not really sure how to get this problem started. If anyone could help me get going or something I can start with. Thank you
