What is the rule for when a force is attractive or repulsive?

How do you determine if a force 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 are the rules of attraction and 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.

What is the force 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.

What is Coulomb’s law explain?

: a statement in physics: the force of attraction or repulsion acting along a straight line between two electric charges is directly proportional to the product of the charges and inversely to the square of the distance between them.

What is attractive and repulsive forces in physics?

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.

Which force is repulsive in nature in addition to attractive?

Coulomb force, also called electrostatic force or Coulomb interaction, attraction or repulsion of particles or objects because of their electric charge.

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.

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.

What is the law of attraction and repulsion in magnetism?

Any object that exhibits magnetic properties is called a magnet. … The law states that the force of attraction or repulsion between two magnetic poles is directly proportional to the product of the strengths of the poles and inversely proportional to the square of the distance between them.

What is repulsion short answer?

1 : the action of repulsing : the state of being repulsed. 2 : the action of repelling : the force with which bodies, particles, or like forces repel one another. 3 : a feeling of aversion : repugnance.

When can you say that an object have a repulsive force between them?

The constant ke is called Coulomb’s constant and is equal to 14πε, where ε is the electric constant; ke = 8.988×109 N⋅m2⋅C2. If the product q1q2 is positive, the force between the two charges is repulsive; if the product is negative, the force between them is attractive.
