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

Contents

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.

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

If the particles are both positively or negatively charged, the force is repulsive; if they are of opposite charge, it is attractive.

## Which force is attractive and repulsive?

Note:It is to be noted that the gravitational force is always attractive in nature. Whereas the electrostatic force is either attractive or repulsive. There exists a force of attraction for like charges and force of repulsion for unlike charges.

## Which forces are repulsive?

Repulsive force (magnetism) between magnets of opposite orientation. A compressed material repelling bodies on both sides, e.g. according to Hooke’s law. Repulsive force (biology), associated with involuntarily vomiting, as in response to ingestion of a toxin.

## What does it mean if a force is attractive?

Definitions of attractive force. the force by which one object attracts another. synonyms: attraction. Antonyms: repulsion, repulsive force. the force by which bodies repel one another.

## 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.

## Is the force between two like masses attractive or repulsive?

Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges. The size of the force varies inversely as the square of the distance between the two charges.

## What causes the attractive and repulsive forces in the atomic model?

(12/14) “It is a matter of attraction. The electrons are attracted to the nuclei because the nuclei are positive and the electrons are negative.” Chemical bond involves both attraction and repulsion forces.

## What makes an electrostatic force attractive or repulsive?

Electric field

If two charges have the same sign, the electrostatic force between them is repulsive; if they have different sign, the force between them is attractive.

## What are repulsive forces chemistry?

Intermolecular forces are the attractive or repulsive forces between molecules. … Short range forces tend to be repulsive, where the long range forces that act outside the three angstroms range are attractive. Long range forces are also known as Van der Waals forces.

## Why are repulsive forces positive?

You would have learnt this thing in chemistry (In Atom Structure, you would have calculated energy of electrons for different energy levels b/w electron & proton(nucleus)), that attractive force reduces the energy of the electrons and repulsive force increases the energy of electrons) So since energy corresponding to …
