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?,

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:

4800 N

GIVEN:

F = 2400 N = 2400 kgm/s/s

g = 10 m/s/s

m = ? kg

1ST SOLUTION:

Lets first find the mass using this formula F = mg.

F = mg

2400 N = (m)(10 m/s/s)

2400 kgm/s/s = (m)(10 m/s/s)

(2400 kgm/s/s) / (10 m/s/s) = m

240 kg = m

Since mass should be doubled, then...

240 kg x 2 = 480 kg

We were looking for the new Force. We. then, use the new mass for the new Force.

F = mg

where:

F = ?

m = 480 kg

g = 10 m/s/s

2ND SOLUTION:

F = mg

F = (480 kg)(10 m/s/s)

F = 4800 kgm/s/s

F = 4800 N.
