Calculate the gravitational force of attraction between two metal spheres each of mass
90 kg, if the distance between their centres is 40 cm.Given G = 6.69 x 10 Nm² kg².will the force of attraction be different
if the same bodies are taken on the moon,
their separation remaining the same?​

Answer:

\huge\underbrace\mathcal{AnsWER}

The universal law of gravitation states that the force of attraction between any two objects is proportional to the product of their masses and inversely proportional to the square of the distance between them.

As given here F=GM1×M2R2

Where M1 = Mass of earth, M2 = Mass of moon, R = Distance between earth and moon. G is the gravitational constant. The above law applies to all objects anywhere in the universe. This is also true in case of force of attraction between Earth and moon. The magnitude of force (F) of attraction exerted by Earth on the moon, due to gravitation, is the same as that exerted by moon (F) on earth.These forces being equal and opposite, also in accordance with Newton's Third Law of Motion, which states that to every action there is an equal and opposite reaction.
