Quick Answer: Which forces can be attractive?

Which type of force is only attractive?

The gravitational force is the only force that is purely attractive.

Can a positive force be attractive?

If the particles are both positively or negatively charged, the force is repulsive; if they are of opposite charge, it is attractive. This called Coulomb’s law and was the first attempt to understand the electric force.

What are forces of attraction?

a force between two bodies, molecules, particles, or the like, that attracts each to the other. … Gravity is the force of attraction between two bodies that have mass.

Is magnetic force always attractive?

Magnetic forces are non contact forces; they pull or push on objects without touching them. Magnets are only attracted to a few ‘magnetic’ metals and not all matter. Magnets are attracted to and repel other magnets.

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 are attractive forces in chemistry?

Intermolecular forces are the forces of attraction or repulsion which act between neighboring particles (atoms, molecules, or ions ). These forces are weak compared to the intramolecular forces, such as the covalent or ionic bonds between atoms in a molecule.

How do you find the attractive force?

Calculate the force of attraction according to F = k * q1 * q2 / d2.

What makes a force attractive?

If the particles are both positively or negatively charged, the force is repulsive; if they are of opposite charge, it is attractive. … The Coulomb force F on a charged particle due to another charge can be obtained by multiplying the electric field caused by by the charge .

Can electric force be attractive and repulsive?

Both equations show an inverse square relationship between force and separation distance. … Second, gravitational forces are only attractive; electrical forces can be either attractive or repulsive.

Why are attractive forces taken as negative?

That’s all right,but I want to know whenever we use a work done by an attraction force we use a negative sign,viz: the gravitational potential.It is written in books that the gravitational potential is negative because the work to bring an object from infinity to the gravitational field is done by the gravitational
