Two asteroids are separated by a distance of 42.0 m. If one asteroid has a mass of 2.22 x 109 kg and the other asteroid has a mass of 9.87 x 108 kg, what is gravitational force between them?
The gravitational force between two asteroids is given by the Newton's law:
where "m_1 = 2.22\\times 10^9 kg", "m_2 = 9.87\\times 10^8kg" are masses of the asteroids, "r = 42m" is the distance between the asteroids, and "G = 6.67\\times 10^{-11}m^3kg^{-1}c^{-2}". Combining it all together, obtain:
Answer. "7.73\\times 10^4N".
