The masses of two object are doubled and the distance between them is halved then the gravitational force acting between them becomes...........Options =>1. remains constant2. Decrease by 63%3. Decrease by 89%4. Decrease by 89%.....(I need full solution cause i have ans and i am not getting question) ​

Answer»

Gravitational FORCE between two objects is given as

F = GMM / d²

Now, let's say

100% = GMm/d² ......(1)

After masses are doubled and distance halved

F' = G(2M × 2m) / (d/2)²

= 4GMm / (d²/4)

= 16Gmm/d²

From equation (1)

= 16 × 100%

= 1600%

%CHANGE in force = 1600% - 100% = 1500%

OPTIONS which you've provided might be of a different question.
