# Two objects attract each other with a gravitational force of magnitude 1.0 x 10-8N when separated by 20.0 cm If the total mass of the object is 5.0 kg what is the mass of each?

m1 + m2 = 5 kg

F = 1 x 10-8 N

G = 6.67 x 10-11 N m2/kg2

r = 0.2 m

F = (Gm1m2) / r2

1 x 10-8 N = (6.67 x 10-11 N m2/kg2)(m1)(5-m1)

divide by 6.67 x 10-11 N m2/kg2

6 = 5m1 - m12

m12 - 5m1 + 6 = 0

(m1 - 3)(m1- 2) = 0

m1 = 3 kg

m2 = 2 kg

### As the mass of two objects increases how does the gravitational force between the two bodies change?

### What affects the magnitude of gravitational force?

Gravitational Force = Gravitational Constant x mass of the first object x mass of the second object / distance squared. So what affects the magnitude is the masses of the objects and the distance between them. Gravitational Constant = 6.672 x 10^-11 N x m^2/kg^2 Both masses, and the distance between them.

### Why do some pairs of objects attract or repel each other?

The gravitational force between two objects always acts to attract them together. Electrically charged objects can attract if they have opposite charges, or repel if they have the same type charge. Thus only gravity could have caused matter in the universe to condense together and eventually form stars and planets.

### What is the most affected by gravitational force?

Gravitational force is experienced by each and every object in this universe.and the magnitude of this gravitational force is proportional to the mass of the object.Hence objects which possess greater mass experience greater gravitational force.the reason of existence of our solar system is the gravitational force experienced by the planets.

### Why isn't time a variable that affects the amount of gravitational force between two objects in space?

To calculate the gravitational force between two objects, all you need is the mass of those two objects, and the distance between their gravitational centers. If You know that, you can calculate the magnitude of the force, and it doesnÂ´t matter if that situation occurs right now, in 2 days, or in 1357. If you want anything to change (force magnitude, distance or whatever you want), of course, you need time, but you cannot make…

### How does the size and distance of two objects affect gravitational pull and apparent magnitude of the objects?

The size of the objects has no effect on the gravitational forces between them. The magnitude of the forces depends on the product of their masses, which are not necessarily related to their size. -- The gravitational force between them decreases according to the square of the distance between their centers. That means that if the distance doubles, the force becomes 1/4 as great, and if the distance multiplies by 5, the force becomes…

### Explain newtons law of universal gravitation?

It states that all objects in the universe attract each other with gravitational forces. The strength of the forces depends on the product of the masses of the objects, and on the distance between them.. therefore the forces between objects increase as the masses of the objects increase, and decrease as the distance between them increases.

### Is gravitational field scalar or vector?

The gravitational force fields are both scalar and vector. The forces are the first derivative of the energy. The derivative is a Quaternion derivative X=[d/dr,Del]. The total energy is W = -mGM/r + cP and there are five forces, F = XW= [d/dr,Del][-mGM/r, cP] = [vp/r -cDel.P, cdP/dr - Del mGM/r + cDelxP] The scalar forces are : vp/r centripetal scalar force -cDel.P= -cp/r cos(PR) centrifugal scalar force the vector forces are: cdP/dr = -cp/r…

### Why is Newton's Law of Universal Gravitation called Universal?

Newton's law of universal gravitation is about the universality of gravity. He discovered that gravitation is universal. All objects attract each other with a force of gravitational attraction. Gravity is universal. This force of gravitational attraction is directly dependent upon the masses of both objects and inversely proportional to the square of the distance that separates their centers.

### What happens with two objects of different charges?

A positively-charged object will attract negatively-charged objects and repel positively-charged objects. A negatively-charged object will repel negatively-charged objects and attract positively-charged objects. Negative or positive charges will slightly attract neutral objects. Neutral objects do not attract or repel each other. General Rules: 1. Like repels like. 2. Opposites attract.
