Concept:

  • Newton’s law of gravitation: According to this law- When two objects having some masses are placed at a certain distance then the gravitational force is directly proportional to the product of masses and it is inversely proportional to the square of the distance between them.

 

Where G is gravitational constant, r is the distance between two masses, m1 and m2 are the masses.
