Objects 1 and 2 Attract each other with a. Gravitational force of 36 units. If the distance separating objects one and two is tripled and the new gravitational force will be

12 units

Explanation:

The formula force for calculating the gravitational force between two masses is expressed as:

F = GMm/d²

M and m are the masses

d is the distance between the masses

If Objects 1 and 2 attract each other with a gravitational force of 36 units, then;

36 =  GMm/d₁² 1

If the distance us tripled, new distance will be 3d₁. The gravitational force between them will be expressed as:

F = GMm/3d₁² 2

Divide equation 1 by 2:

36/F = GMm/d₁²÷GMm/3d₁²

36/F = GMm/d₁²×3d₁²/GMm

36/F = 3d₁²/d₁²

36/F = 3/1

Cross multiply

3F = 36

F = 36/3

F = 12 units

Hence if the distance between the masses is tripled, the new gravitational force will be 12 units
