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?

600 N
1200 N
4800 N
9600 N

Answer 1

4800N 100%
(2m1m2/r^2)/(m1m2/r^2)

Answer 2

By definition, the gravitational force of two objects is given by:

`image`

Where,

G: gravitational constant

m1: object number 1

m2: object number 2

r: distance between objects

Suppose that one of the masses is twice its initial value.

We have then:

`image`

Rewriting the equation we have:

`image`

Substituting values:

`image`

Answer:

the gravitational force between the objects if the mass of one object is doubled is:

4800 N
