Answer to Question #169006 in Physics for aj

Question

Two spherical objects have masses of 8000 kg and 1500 kg.  Their centers are separated by a distance of 1.5 m.  Find the gravitational attraction between them.

Answer 1

$$F=\dfrac{Gm_1m_2}{r^2},$$ $$F=\dfrac{6.67\cdot10^{-11}\ \dfrac{Nm^2}{kg^2}\cdot8000\ kg\cdot1500\ kg}{(1.5\ m)^2}=3.56\cdot10^{-4}\ N.$$
