Question

1.Find the force between two objects when ,their masses and the distance are doubled


2.State Universal law of gravitation and write its importance.​

Answer 1

1The gravitational force between two objects is inversely proportional to the square of distance between them.

So, if the distance between two objects is doubled, then the gravitational force becomes

2×2

1

.

That is, 1/4.

Therefore, if the distance between two masses be doubled, then the force between will becomes 1/4.

2 Gravity is what pulls us toward Earth, but it's also what pulls Earth toward us. This is explained by the law of universal gravitation, which describes how all objects in the universe have this important force between them.
