According to the inverse-square law of gravitaion, the force of gravitation on a planet should decrease as the square of the distance of the planet from the sun. Newton further showed that the gravitational force is proportional to the product of the masses of the two objects. Thus, Newton <a href="https://interviewquestions.tuteehub.com/tag/formulated-996896" style="font-weight:bold;" target="_blank" title="Click to know more about FORMULATED">FORMULATED</a> the universal law of gravitation.Read more on Sarthaks.com - https://www.sarthaks.com/869554/how-did-newton-guess-the-inverse-square-rule</p></body></html> | |
