How are the equations for gravitational force and electrostatic force are similar?

The force equations are similar, so the behavior of interacting masses is similar to that of interacting charges. The main difference is that gravitational forces are always attractive, while electrostatic forces can be attractive or repulsive. Charge plays the same role for electrostatics that mass plays for gravity.

What is the difference between electrostatic force and gravitational force?

The differences are: Electrostatic force is force between two charges separated by distance in space while gravitational force is the force between two masses separated by a distance. Electrostatic force is either repulsive or attractive while gravitational force is always attractive.

How are gravitational and electric fields similar?

Electric fields are similar to gravitational fields – both involve action-at-a-distance forces. In the case of gravitational fields, the source of the field is a massive object and the action-at-a-distance forces are exerted upon other masses.

What is the relationship between electrostatic force and gravitational force?

Gravitational force is proportional to the masses of interacting objects, and the electrostatic force is proportional to the magnitudes of the charges of interacting objects. Hence both forces are proportional to a property that represents the strength of interaction for a given field.

What do gravity and electricity have in common?

Electric forces, like gravitational forces, are one of the four fundamental forces of the universe, and because of this, they have many similarities. Just like objects that have mass exert gravitational forces on each other, objects that are charged will also exert electric forces on each other.

What are the similarities and differences between gravitational and electrostatic forces?

They both act between two bodies without any means of contact. However gravitational force acts on mass while the electric force acts on charge. Gravitational force are only attractive while electric field can be attractive/repulsive. Electric field is much stronger than gravitational field.

What is the relation between electrostatic force and gravitational force?

Why is electrostatic force stronger than gravitational force?

The gravitational force is directly proportional to the mass of both objects. The electrostatic force is directly proportional to the charge of the objects. Therefore, gravitational forces dominates.

Is electrostatic force equal to gravitational force?

The electrostatic force between two subatomic particles is far greater than the gravitational force between the same two particles.

What is the equation for calculating the electric force Fe?

Since we know the electric field strength and the charge in the field, the force on that charge can be calculated using the definition of electric field E=Fq E = F q rearranged to F = qE.

Why do electrostatic forces have static in their name?

Electric force exists between charges, as described by Coulomb’s Law. Electrostatics deals with forces between charges. Static means the charges are not moving, or at least are not moving very fast.
