Electrical & gravitational force:which one is stronger?

In summary, there is a contradiction in texts regarding the strength of electrical/electrostatic force compared to gravitational force. While gravitational force is considered the weakest of the four fundamental forces, the strength of the forces can vary depending on the masses and charges of the objects involved. A direct comparison can only be made in terms of coupling strength, not the force itself.

I know that electrical/electrostatic i.e Coulob force is stronger than gravitational fiorce.But how much?There's too much contradiction within texts.

Homework Equations



Fe=Kq1q2/r2

Ge=Gm1m1/r2

The Attempt at a Solution



Different figures've been found in texts.Plz. give accurate figure.

Surely it depends upon the charges and masses of the particles you are considering. Why not decide on a situation, then put some numbers in and find out?

well...are you talking about the hierarchy problem? mmm... seems a bit advance for intro physics. OK, yes gravitational "force" is the weakest of all 4 fundamental forces (loosely speaking), but as previous poster said, it can also depend on the mass/charge of the objects involved. A direct comparsion can only be done when you are talking about coupling strength and not the force itself.
 

1. Is electrical force stronger than gravitational force?

It depends on the objects involved. Generally, the electrical force between two charged particles is much stronger than the gravitational force between them. However, on a larger scale, such as planetary or cosmic objects, the gravitational force can be much stronger.

2. What is the formula for calculating electrical force?

The formula for electrical force is F = k * (q1 * q2) / r^2, where k is the Coulomb's constant, q1 and q2 are the charges of the two objects, and r is the distance between them.

3. How does the distance between two objects affect the strength of the gravitational force?

The gravitational force is inversely proportional to the square of the distance between two objects. This means that as the distance between two objects increases, the gravitational force between them decreases.

4. Can electrical force and gravitational force cancel each other out?

No, they are fundamentally different forces and cannot cancel each other out. However, they can both act on the same object simultaneously.

5. What is the relationship between electrical force and gravitational force?

There is no direct relationship between these forces. They are both fundamental forces of nature and act independently of each other.
