# How do you know if something is attractive or repulsive?

Contents

If the particles are both positively or negatively charged, the force is repulsive; if they are of opposite charge, it is attractive.

## What is the difference between attractive and repulsive force?

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. Because the nuclei are positive and the electrons are negative, the electrons are attracted to the nuclei.

## 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.

## What can apply an attractive or repulsive force?

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 negative force repulsive or attractive?

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).

## 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.

## 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 causes attraction repulsion?

In contrast to the attractive force between two objects with opposite charges, two objects that are of like charge will repel each other. That is, a positively charged object will exert a repulsive force upon a second positively charged object. … Objects with like charge repel each other.

## 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?

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 this electrostatic force attractive or repulsive?

The electrostatic force is also known as the Coulomb force or Coulomb interaction. It’s the attractive or repulsive force between two electrically charged objects. Like charges repel each other while unlike charges attract each other.

## 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.

## Is electromagnetic force attractive or repulsive?

Electromagnetism is both an attractive and repulsive force between particles with a property called charge, which come in two varieties – positive and negative. Objects of like charge will have a repulsive effect on each other, while objects of unlike charges will have an attractive effect.

## Is positive force always repulsive?

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.

## Is negative potential attractive?

Remember the rule: Opposites attract; Likes repel. A positive charge would be repelled by something that already has a positive potential, while a negative charge would be attracted to the very same object.

## Does a negative force implies attractive 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.
