Which forces can be attractive as well as repulsive?

Which type of force can have both attractive and repulsive forces?

Unlike the other two fields, which can involve both attraction and repulsion, gravity only acts by attraction. All objects attract each other by gravity, but these attractions are too weak to notice unless one object contains a huge amount of matter (stuff).

Are there attractive and repulsive forces?

Attraction is a force between two charges that are distinct or unlike. Because the nuclei are positive and the electrons are negative, the electrons are attracted to the nuclei. … Repulsive forces occur only when atoms are very close to each other.

Which of the following forces is attractive as well as repulsive in nature?

Answer: gravitational force is always attractive in nature. electromagnetic force can be attractive or repulsive.

Are intermolecular forces attractive or repulsive?

Intermolecular forces are repulsive at short distances and attractive at long distances (see the Lennard-Jones potential). In a gas, the repulsive force chiefly has the effect of keeping two molecules from occupying the same volume.

Is magnetic force attractive or repulsive?

magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron.

What is an repulsive force?

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 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.

Which of the following forces are always attractive?

The correct answer is option 2 i.e. Gravitational force. All objects in the universe attract each other. This force of attraction between objects is called the gravitational force.

Which of the following forces are always attractive in nature?

(a) Gravitational force is always attractive in nature.

Which of these forces is only attractive in nature?

Grade 9. 1) gravitational force is the only attractive force.

How do you know if attractive or repulsive forces dominate?

For example, when attractive forces dominate, the real gas will have a smaller volume than the ideal gas, as the attractive forces pull the particles closer together. The reverse is true when repulsive interactions dominate. … Z 1: Repulsive forces dominate, and the gas occupies a larger volume than an ideal gas.

What is attractive force?

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.

Are van der Waals forces repulsive?

Van der Waals forces may be attractive or repulsive, depending on the distance between the molecules involved. Recall that Van der Waals forces generally refer to intermolecular forces . These forces are generally attractive at normal pressures. … If the opposite is true, the molecules will repel.
