Question

The gravitational force between two objects is 2400 N. What will be the gravitational force between the objects if the mass of one object is doubled

600N
1200N
4800N
9600N

Answer 1

4800N

Step-by-step explanation:

Lets assume,

Mass of first object = m₁

Mass of second object = m₂

Distance between the two objects = r

Thus the force between the two objects will be

`F = (G* m_(1)* m_(2))/(r^(2))`

where, G = Universal gravitational constant

Given, F = 2400N

New mass of second object = 2m₂

Now, the force will be

`F_(2) = (G* m_(1)* 2m_(2))/(r^(2))`

`F_(2)= 2(G* m_(1)* m_(2))/(r^(2))`

`F_(2)= 2F`

`F_(2)= 2*2400`

Thus, F₂ = 4800N
