two spaceships of mass 300,000 kg are 250 m apart. what is the force of gravity between them? (G= 6.67 times 10⁻¹¹ N×M²/kg²)

Respuesta :

F = G.m1.m2 / d² 

F = [6.67*10^-11 * (3*10^5)²] / (2.5*10^2)²

F = (6.67*10^-11 * 9*10^10) / 6.25*10^4 

F = 6 / 6.25*10^4

F = 0.96*10^-4 N

The right answer is 9.6 x 10^-5
