Answer to Question #325195 in Physics for kei

Question

Two spherical objects have masses of 7.5 x 10⁸ kg and 6.5 x 10⁸ kg. Their centers are separated by a distance of 2.5 x 10⁶ m.

Answer 1

The gravitation force between spheres

$$F=G\frac{m_1m_2}{r^2}$$

$$F=6.67*10^{-11}*\frac{7.5*10^8*6.5*10^8}{(2.5*10^6)^2}=5.2*10^{-6}\:\rm N$$
