How do you know if something 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’s the difference between attractive and repulsive forces?

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.

What is definition 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.

How do you know if an electrostatic force is attractive or repulsive?

The Coulomb force between two or more charged bodies is the force between them due to Coulomb’s law. If the particles are both positively or negatively charged, the force is repulsive; if they are of opposite charge, it is attractive.

Which of the following force is both attractive and repulsive?

Therefore, the electrostatic force is a non contact force which may be both attractive and repulsive in nature.

What is repulsive energy?

In quantum mechanics, a repulsive state is an electronic state of a molecule for which there is no minimum in the potential energy. … This condition is also known as predissociation since the chemical bond is broken at an energy which is lower than what might be expected.

What are repulsive forces?

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

Is gravitational force attractive or repulsive?

Gravitational force -an attractive force that exists between all objects with mass; an object with mass attracts another object with mass; the magnitude of the force is directly proportional to the masses of the two objects and inversely proportional to the square of the distance between the two objects.

What causes attraction repulsion?

The force between two wires, each of which carries a current, can be understood from the interaction of one of the currents with the magnetic field produced by the other current. It is repulsive if the currents are in opposite directions. …

What is a electrostatic attraction?

Electrostatic attraction is essentially the attraction between the positively charged nucleus of an atom and the negatively charged electrons surrounding it. The greater the positive charge of the nucleus (the more protons), the greater the effective nuclear charge.

What is magnetic attraction?

Noun. 1. magnetic attraction – attraction for iron; associated with electric currents as well as magnets; characterized by fields of force. magnetic force, magnetism. attraction, attractive force – the force by which one object attracts another.

Is a negative electric force attractive or repulsive?

According to Coulomb, the electric force for charges at rest has the following properties: 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.

Can positive force be both attractive and repulsive?

Regarding force (c)A positive force can be both attractive and repulsive in nature. Explanation: The force is repulsive if the particles are both positively or negatively charged; it is attractive if they are of opposite charge.

Are electrostatic forces always attractive?

The electrostatic force is a very large force. There are two types of charges: positive charges and negative charges. Like charges repel each other and unlike charges attract each other. Therefore, electrostatic forces are not always attractive.
