## How do you determine if a force is attractive or repulsive?

**If both the interacting particles are positively or negatively charged**, then the force is repulsive. If both the interacting particles are of opposite charges then the force is attractive in nature.

## What is the attraction or repulsion of two objects?

Coulomb force, also called electrostatic force or Coulomb interaction, attraction or repulsion of particles or objects because of their electric charge.

## What are the factors that influence the force of attraction repulsion between charges?

In an atom, the most important factors that influence the force, as calculated by Coulomb’s equation, are **the nuclear charge and the distance from the nucleus to the electron of interest**. The closer an electron is to a nucleus, the stronger the attractive force (i.e. the more negative F becomes).

## What is the force of attraction and repulsion?

Attraction is a **force between two or more dissimilar or** unlike charges. Two charges of dissimilar characteristics pull towards each other. Repulsion is a force between two or more similar or like charges. Two charges of similar characteristics pull away from each other.

## What is attractive and repulsive forces in physics?

Repulsion is a movement between two charges that are identical or similar. The power that exists between two electrons (negative charge). Attraction is a force between two charges that are distinct or unlike. … Repulsive forces occur **only when atoms are very close to each other**.

## How do you find the force of attraction?

The mathematical formula for gravitational force is **F=GMmr2 F = G Mm r 2** where G is the gravitational constant.

## What factors affect electric force between two objects?

In electrostatics, the electrical force between two charged objects is **inversely related to the distance of separation between the two objects**. Increasing the separation distance between objects decreases the force of attraction or repulsion between the objects.

## What will happen to the electrostatic force between 2 objects if the distance between them is is doubled?

The size of the force varies inversely as the square of the distance between the two charges. Therefore, if the distance between the two charges is doubled, **the attraction or repulsion becomes weaker, decreasing to one-fourth of the original value**.

## What two factors have an affect on the force between the two charges seen in the simulation?

Charles Coulomb determined how to figure out the strength of the force between charged particles. As we’ll discuss in this lesson, he found that the force between charged particles was dependent on only two factors: **the distance between the particles and the amount of electric charge that they carried.**

## What determines the direction of electric force between two charges?

The direction of the force vector depends on **the sign of the charges**. If the charges are the same, the force points away from the other charge. If the charges have different signs, the force points toward the other charge((Figure)).

## On what factors does the electrostatic force between two charges depends and how?

The electrostatic force between two charges depend on the following factors; **value of charges on them,** **distance between them, and**. **nature of medium between them**.
