1.
gamma0 = KxMp/r1^2
gamma1 = KxMp/r2^2
gamma1 = gamma0/36
=> KxMp/r1^2 = (KxMp/r2^2) x 1/36
=> KxMpxr2^2x36 = KxMpxr1^2
=> 36r2^2 = r1^2
=> la o distanta de 36ori mai mare fata de punctul de referinta
2.
raza Lunii = 1730 km, 7,34×10^22 kg adica 0,012300 din a Pământului
raza Pamantului = 6371 km, masa = 5,97×10^24 kg
Fg.L = KxM.L/R.L² = Kx0,0123xMP/1730² = 2,45x10^16
Fg.P = KxM.P/R.P² = KxM.P/6371² = 1,47x10^17
=> Fg.L / Fg.P = 2,45x10^16 / 1,47x10^17 = 0,167
