Question

Force between two masses is 20N if their masses become doubled and distance between them is halved, then find new force​

Answer 1

Answer:

320 N

Explanation:

We know that F = GMm/R² = 20 N

Here according to the question the new equation would be : New F = G (2)M (2)m/ (R/2)²

= 4GMm/R²/4 = 16GMm/R²

Now we already know that GMm/R² is 20 so substitute in the following equation and we get :

New F = 16 X 20

= 320 N

Answer 2

Answer

*The correct answer is force would be 16 times the initial force .

Explanation:

There is no change in the force since gravitational force is directly proportional to the masses and inversely proportional to the square of the distance
