Question

find the change in the force if two masses are shifted to one third of their original distances. keeping the masses same​

Answer 1

Explanation:

The gravitational attraction between two objects is inversely proportional to the square of the distance between them.

If the distance between them is increased by three times, the new distance between them would be four times the earlier distance.

Hence, the force of attraction between them would decrease to a value which is one-sixteenth of the earlier force.

Edit: Please note the following.

Let the initial distance be r.

Increased to 3 times the original distance means the new distance is 3r.

Increased by 3 times the original distance means the new distance is the original distance r plus the increase in distance 3r totalling 4r
