Question

When two objects with masses of 200 kg and 500 kg were tested for gravitational attraction. Their centers were separated by a distance of 25 m. Find the force of gravitation between them. (ex: 6.57x10^10 N)

Answer 1

The force of gravitation between them is

$$F=G\frac{m_1m_2}{R^2},\\\space\\ F=6.673\cdot10^{-11}\frac{200\cdot500}{25^2}=1.07\cdot10^{-8}\text{ N}.$$
