What are 2 things that affect how strong an electric force is?
▪ An electric fields strength is dependent on two things:
- Strength of the charge.
- Distance from the charge.
- Friction.
- Conduction (Direct Contact)
- Induction.

What 2 factors determine the strength of electric force fields?
The new formula for electric field strength (shown inside the box) expresses the field strength in terms of the two variables that affect it. The electric field strength is dependent upon the quantity of charge on the source charge (Q) and the distance of separation (d) from the source charge.
What makes an electric force stronger?
When you have two charged particles, an electric force is created. If you have larger charges, the forces will be larger. If you use those two ideas, and add the fact that charges can attract and repel each other you will understand Coulomb’s Law.
What determines electric force?
Electrical forces result from mutual interactions between two charges. In situations involving three or more charges, the electric force on a single charge is merely the result of the combined effects of each individual charge interaction of that charge with all other charges.
Which force is attractive?
gravitational force
The gravitational force is the only force that is purely attractive. Electricity and magnetism can be repulsive as well. For all three forces, the closer the objects are to each other, the stronger the force of attraction. When the objects are far apart, the force of attraction is weaker.
What force can be repulsive or attractive?
Concept Connections: The Four Basic Forces
Force | Approximate Relative Strengths | Attraction/Repulsion |
---|---|---|
Gravitational | 10−38 | attractive only |
Electromagnetic | 10–2 | attractive and repulsive |
Weak nuclear | 10–13 | attractive and repulsive |
Strong nuclear | 1 | attractive and repulsive |
What are the two things that the electric force depends on?
The amount of each charge and the distance between the charges. The two things that the electric force depends on is the distance and amount of each charge. The electric force is a repulsive interaction. This interaction is between electrons and the nucleus. Research has shown that the electric force between the two objects is proportional.
Which is greater the force of gravity or the electric charge?
Electric charge is the property of objects that gives rise to this observed force. Like gravity, electric force “acts at a distance”. The idea that a force can “act at a distance” is pretty mind-blowing, but it’s what nature really does. Electric forces are very large, far greater than the force of gravity.
How to calculate the magnitude of an electric force?
The individual force vectors are on a direct line between the charge pairs. For simplicity, we’ll use as the proportionality constant. Apply Coulomb’s Law to compute the force. We manage the magnitudes and angles separately. The magnitudes of the forces are, We have solved the magnitudes of the pairwise forces.
How to find the force between two charges?
Find the force (magnitude and direction) on , the charge. Compute the force between each pair of charges. In this example there are two force vectors to think about, { to }, and { to }. The individual force vectors are on a direct line between the charge pairs.
