Question

What is the inverse square rule and how did newton guess it?

Answer 1

Answer:

The negative sign indicates that the force is attractive. Newton actually derived his inverse square law from Kepler's third law of planetary motion which states that, “The square of time period of a planet around the sun is directly proportional to the cube of the semi-major axis of the orbit”.
