Answer to Question #268232 in Electric Circuits for Ellah

Question

Two spherical objects have masses of 250 kg and 550 kg. Their centers are separated by a distance of 45 m. Find the gravitational attraction between them.

Answer 1

$F = \frac{Gm_1m_2}{r^2} \\ F = \frac{6.67 \times 10^{-11} \times 250 \times 550}{45^2} = 4.53 \times 10^{-9} \;N$
