Two small masses that are 10 cm apart attract each other with a force of 10 N when they are 5 cm apart these masses will attract each other with what force?

Answer #1:
Reading between the lines, this has to be the electrostatic force.
Two "small masses" at that distance couldn't possibly attract each other with
that much force due to gravitation.
The other two forces (the weak and strong nuclear forces) have ranges that
are much much less than that.
If you wanted the number rather than the name of the force, then you just
need to look up Coulomb's Law and find how it varies by distance (the r squared
term should be a clue here). Halving the distance multiplies the force by 4.
================================
Observation:
Answer #1 is correct, and stunningly perspicacious as well.
If the centers of these masses are 10m apart and the gravitational force
between them is 10 N, then the product of the masses is 1.5 x 1013 kg2. (rounded)
You've said that they can be moved to where their centers are 5m apart.
So if, say, they are spheres, then their radii can't sum to more than 5m.
Let's say that they are two spheres with equal size and equal mass. Then for
each one, the radius is 2.5m, the volume is 65.45 m3, the mass is 3.87 x 106 kg,
and the density is 59,175 gm/cm3 .
Just now, I have nothing to compare that density to, so I'm not sure whether
you have a pair of baby black holes there, or simply a few cupfulls of plain old
nuclear fluid or Sirius-B.

∙ 12y ago-- You remember when the class was learning that the mutual forces of gravity
are inversely proportional to the square of the distance between the masses.
-- You scratch your head wondering what the heck that means.
-- You take it to a friend who was awake and listening that day, and he explains how
it means that when you cut the distance in half, the force becomes 4 times stronger.
-- As soon as you hear that, you realize how easy the problem is, and you whip out
the answer with no trouble at all.

What are gravitonal forces?
The force of gravity is a force between any masses. The force is always attractive. Larger masses attract one another more strongly; on the other hand, at greater distances the force is less.
How are gravity weight and mass related?
Gravity is the cause of forces that attract every pair of masses toward each other. If one of the masses is the Earth and the other one is you, then you call the force your "weight".
What does the Electric Force between two charged objects depend on A Their masses and their separation B Their speeds C their charge and their separation D their masses and their charge?
Well, an electric force can be attractive or repulsive and it is the STRONGEST force in nature. And to feel this force, small changes might be involved.So, the question is: The Electric Force between two charged objects depends on which of the following?A) Their masses and their separationB) Their speedsC) their charge and their separationD) their masses and their chargeAnswer: C) Their charge and their separation.Why? Because the force between electric charges depends on the distance between charges (the force decreases as the charges get farther apart) and it depends on the force the electric charges exert on each other. And negative charge and positive charge do attract but positive and positive charge don't attract and negative and negative don't attract.
What are the two properties of the pull of gravity?
-- It always attracts, never repels. -- The gravitational force is always equal on both of the masses that attract each other.
What does it mean when two magnets attract?
Obviously two magnets are bonded with each other and can only be pulled apart by another force.

Why does earth attract near by objects with significant force?
A force called "gravity" makes that any mass attract any other mass. The larger the masses, the stronger will the force be. The greater the distance, the smaller will this force be.
Two objects attract each other gravitationally with a force of 2.5 10-10 N when they are 0.29 m apart Their total mass is 4.0 kg Find their individual masses?

How is occur gravitation?
Gravity is an effect of mass. Two masses will attract each other proportional to their masses and the force varies by the inverse square of the distance.
If everything in the universe attracts everything why do we not attract each other?
We do! The strength of the force depends on our masses and the distance between us. The gravitational force between two 200-pound people standing 3-feet apart, is about 0.0000024 ounce of force. If one of the people had the mass of the Earth and they stood 4,000 miles apart, then the force would be 200 pounds.
How are gravity weight and mass related?

What force that gravity exerts on an object is called?
The mutual force with which every two masses attract each other because of gravity is referred to as the "weight" of the objects.

State newton's law of gravitation?
the law was," Every matter in the universe attract each other by a line joining them with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.''From Sambit PalIndia.

Obviously two magnets are bonded with each other and can only be pulled apart by another force.
