Attraction due to charge particles and attraction due to gravity

In summary, we don't understand gravity or what causes it, but we do understand attraction or repulsion due to charge.

Why we don't question attraction of a positive and negative charge particles but we question attraction due to gravity.

We say we do not understand gravity or what causes gravity or attraction. Isn't the attraction due to gravity similar to the attraction or repulsion between charged bodies.

I am aware attraction/repulsion due to charge is due to quarks which too are also charge particles.

what makes you think we don't? There are theories of electro-magnetic force just as there are theories of gravity.

Similar, but not exactly the same. For example, gravity only has one "charge", whereas the EM force has two charges. This causes all objects to attract each other via gravity whereas charged objects will repel or attract each other based on their mutual charges.

That's only true for particles that are made up of quarks. Leptons, which includes particles such as the electron and muon, are not made of quarks and are still electrically charged.

Have you heard of a theory called "general relativity"?

Isn't the attraction due to gravity similar to the attraction or repulsion between charged bodies.

No, it's not, except as an approximation. (a very good approximation under "everyday" circumstances)

Electrical charge is due to charge characteristic of a particle and fundamentally attract or repel. So, is gravity also some characteristic of particles or it is just due to the curvature of space created by particles/matter.

That is true

This causes all objects to attract each other via gravity
but not always.
Two bodies can get away from each other, due to gravity only.
For example,

If we have a stone ball and a helium spherical balloon and they have the same diameter.
And they are surrounded with heavier fluid than Helium.
Air for example.
And let there be only this two bodies and the fluid around them. No other masses.
Due to Gravity, Helium balloon will not get closer to the stone ball, but exactly the opposite -
it will fly away.

Something like this

Gravitational attraction is on the order of 10^37 times weaker than electrostatic attraction.
Both are inverse square laws.
 

1. What is the difference between attraction due to charge particles and attraction due to gravity?

Attraction due to charge particles is a force that exists between two charged particles, where opposite charges attract each other and like charges repel each other. Attraction due to gravity is a force that exists between any two objects with mass, where larger masses attract smaller masses towards each other.

2. How are attraction due to charge particles and attraction due to gravity similar?

Both attraction due to charge particles and attraction due to gravity are fundamental forces in nature that act over a distance. They both follow an inverse-square law, meaning the force decreases as the distance between the objects increases. Additionally, both forces are caused by the exchange of particles: electromagnetic force is caused by the exchange of photons, while gravity is caused by the exchange of gravitons.

3. Which one is stronger, attraction due to charge particles or attraction due to gravity?

In most cases, attraction due to charge particles is stronger than attraction due to gravity. This is because the magnitude of charge is typically much greater than the magnitude of mass. For example, the force of attraction between two protons (due to charge) is about 1036 times stronger than the force of attraction between the two protons (due to gravity).

4. Can attraction due to charge particles and attraction due to gravity cancel each other out?

Yes, attraction due to charge particles and attraction due to gravity can cancel each other out in some scenarios. For example, if two objects with opposite charges have an equal and opposite gravitational force between them, the two forces will cancel out and the objects will remain stationary. This is known as electrostatic equilibrium.

5. How do attraction due to charge particles and attraction due to gravity affect the behavior of matter in the universe?

Both forces play a crucial role in determining the behavior of matter in the universe. Attraction due to charge particles is responsible for holding atoms and molecules together, forming the basis of all chemical interactions. Attraction due to gravity is responsible for larger scale interactions, such as the formation of planets, stars, and galaxies. Without these forces, the universe as we know it would not exist.
