Question

The gravitational force between two objects is 2N. What will be the gravitational force between these objects if the distance between them is doubled ?​

Answer 1

Answer:-

0.5 N

Explanation:-

Given:-

→Gravitational force between two

objects = 2 N

To find:-

→Gravitational force between these

objects if distance between them

is doubled.

Solution:-

By Newton's Universal Law of Gravitation, we know that:-

=> F = GMm/r²

Thus:-

=> 2 = GMm/r². ------(1)

If distance, between the objects is doubles i.e it becomes 2r, then F'(new gravitational force) :-

=> F' = GMm/(2r)²

=> F' = GMm/4r². -----(2)

Now, on dividing eq.2 by eq.1, we get:-

=> F'/2 = [(GMm/4r²)/(GMm/r²)]

=> F'/2 = 1/4

=> F' = 2/4

=> F' = 0.5 N

Thus, the new gravitational force

is 0.5 N.
