Question

.State Newtons universal law of gravitation Suppose that the radius of the
earth becomes twice of its original radius without any change in its mass.
Then what will happen to your weight?


​

Answer 1

Explanation:

Newton’s universal law of gravitation works for the planets, but is it really universal? The gravitational theory should also predict the observed acceleration of the Moon toward Earth as it orbits Earth, as well as of any object (say, an apple) dropped near Earth’s surface. The falling of an apple is something we can measure quite easily, but can we use it to predict the motions of the Moon?
