Can electric forces be attractive?

Second, gravitational forces are only attractive; electrical forces can be either attractive or repulsive. The inverse square relationship between force and distance that is woven into the equation is common to both non-contact forces.

Is electricity an attractive or repulsive force?

The attractive or repulsive interaction between any two charged objects is an electric force. Like any force, its effect upon objects is described by Newton’s laws of motion. The electric force – Felect – joins the long list of other forces that can act upon objects.

Can electric forces attract and repel?

Attraction and repulsion of electric charges is one of three fundamental non-contact forces in nature. … Positive and negative charged objects attract or pull each other together, while similar charged objects (2 positives or 2 negatives) repel or push each other apart.

What is electric force of attraction?

The electrostatic force is an attractive and repulsive force between particles are caused due to their electric charges. The electric force between stationary charged bodies is conventionally known as the electrostatic force.

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 true about electrical forces?

Electric forces can only act between charged objects – either like-charged or oppositely-charged. Electric forces between two charged objects increases with increasing separation distance. Electric forces between two charged objects increases with increasing quantity of charge on the objects.

Which forces can be either attractive or repulsive?

Electric and magnetic (electromagnetic) forces can be attractive or repulsive, and their sizes depend on the magnitudes of the charges, currents, or magnetic strengths involved and on the distances between the interacting objects. Gravitational forces are always attractive.

Is it possible that two like charges attract each other?

yes they can attract each other when one of them is very very large than the other then the electrostatic force acting on the two is not due to their initial charges but will be due to the charges produced due to induction. and hence attraction takes place.

Do positively charged objects attract?

The interaction between two like-charged objects is repulsive. … Positively charged objects and neutral objects attract each other; and negatively charged objects and neutral objects attract each other.

What affects electrostatic attraction?

The charge and size of a ligand atom and/or metal ion can effect the electrostatic attraction between the two, in turn effecting the attractive force between metal and ligand. … In general, the higher the charge, the stronger the attraction between metal and ligand.

Who discovered attraction?

Charles-Augustin de Coulomb invented a device, dubbed the torsion balance, that allowed him to measure very small charges and experimentally estimate the force of attraction or repulsion between two charged bodies.

What is the charge on each of the force is attractive?

If the charges are of opposite signs (one positive, one negative) then the force is mutually attractive and the force on each charge points toward the other one.

Is an attractive force positive or negative?

When the charges have opposite sign, the force is attractive (negative F), while if both charges have the same sign, the force is repulsive (positive F).

Is negative force attractive in nature?

Like charges repel and unlike charges attract. Coulomb’s law describes a force of infinite range which obeys the inverse square law, and is of the same form as the gravity force. … A negative force implies an attractive force. The force is directed along the line joining the two charges.

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.
