Question

How does the gravitational changes between two objects when:

(a) the distance between them is doubled ?
(b) the mass of each is reduced to half ?​

Answer 1

Answer:

(a)According to the law of gravitation, a body attracts other body with a force named as gravitational force.

Mathematically, gravitational force between two objects is directly proportional to the product of their masses & inversely proportional to the square of the distance between them.

According to your question, the distance between the two objects is doubled. Obviously, it will decrease the force by four times as per the law of gravitation.

(b)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.
