Answer 1

Odpowiedź:

3)

r=15km

R=6373km

F1=GMm/R²

F2=GMm/(R+r)²

F2/F1=GMm/(R+r)² / GMm/R²

F2/F1=R²/(R+r)²

F2/F1=6373²km²/6388²km²

F2/F1=0,995

4)

R=150*10⁶km

Mz=6*10²⁴kg

Ms=2*10³⁰kg

Fs=GMs*m/x²

Fz=GMz*m/(R-x)²

Fs=Fz

GMs*m/x²=GMz*m/(R-x)²

Ms/x²=Mz/(R-x)²

Ms/x²=Mz/(R²-2Rx+x²)

x=R√Ms/(√Ms+√Mz)

x=150*10⁶km*√2*10³⁰kg/(√2*10³⁰kg+√6*10²⁴kg)

x=1,5*10⁸km
