Question

what happen to the force of attraction of two objects
a)if the mass of one object is tripled ?
b)if masses of both objects are doubled ?
c)if distance between them is doubled​

Answer 1

Answer:

If the mass of both of the objects is doubled, then the force of gravity between them is quadrupled; and so on. 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.

Answer 2

Answer:

From the relationship,  

(i) If the mass of one object (say body 1) is doubled, then    Thus, the gravitational force between the two objects gets doubled.  

(ii) If the distance between the two objects is doubled, then    Thus, the gravitational force between the two objects becomes one-fourth. If the distance between the two objects is tripled, then    Thus, the gravitational force between the two objects becomes one-ninth.  

(iii) If the masses of both the objects are doubled, then    Thus, the gravitational force between the two objects becomes 4 times.
