Question

How is gravitational force of attraction between two bodies affected if
(i) Mass of both bodies is doubled.
(ii) Distance between them is halved.

Answer 1

Answer:

(i) Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. If the mass of both of the objects is doubled, then the force of gravity between them is quadrupled.

(ii) Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.

Answer 2
