## 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.

## What is the difference between the repulsion and attraction?

Repulsion is a force between two similar or like charges, while Attraction is a force between two dissimilar or unlike charges. … Example: The force between two electrons (negative charge), while In attraction, the two charges of dissimilar nature are pulling toward each other.

## What is the rule for attraction and repulsion between two magnets?

Rule of attraction of magnets states that “when a south pole of a magnet is brought close to the north pole of another magnet, they attract”. Rule of repulsion of magnets states that “when a north pole of a magnet is brought close to the north pole of another magnet, they repel”.

## How do you find the repulsive force?

In the equation Felect = k • Q1 • Q2 / d2 , the symbol Felect represents the electrostatic force of attraction or repulsion between objects 1 and 2.

## Is repulsion positive or negative?

attraction is negative potential energy while repulsion is positive potential energy.

## What causes attraction repulsion?

When two opposite magnetic poles are close, they attract each other. When like poles are pushed together, there is a force of repulsion. The rule for magnets is that like poles repel and unlike poles attract.

## Which has a lower energy a repulsion or an attraction?

As the atoms first begin to interact, the attractive force is stronger than the repulsive force and so the potential energy of the system decreases, as seen in the diagram. Remember that the lower potential energy increases the stability of the system.

## What is the law of attraction and repulsion?

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.

## How will you prove that repulsion is a sure test of magnetism?

Repulsion is the sure test for magnetism because it occurs only when two like poles of a magnet exist while the attraction phenomenon can occur between two unlike poles of a magnet and also between a magnet and a magnetic material means if there are two magnets they will attract each other and suppose if one material
