Question

Q. 1. How does the force of gravitation between two objects change when the
distance between them is reduced to half?​

Answer 1

Answer:

The force of gravitation between two objects is inversely proportional to the square of the distance between them therefore the gravity will become four times if distance between them is reduced to half.

Answer 2

Answer:

The force of gravitation between two objects change when the distance between them is reduced to half as the force of attraction acting between two body is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

F = $G \frac{m_{1} m{2}}{r^{2}}$

• Here, G is a constant of proportionality.

• It is known as gravitational constant.

• The value of G remains the same at all places.

• It is a universal constant and therefore known as universal gravitational constant.
