Why can the electric force be attractive or repulsive?

The Coulomb force between two or more charged bodies is the force between them due to Coulomb’s law. If the particles are both positively or negatively charged, the force is repulsive; if they are of opposite charge, it is attractive.

Can electric force be attractive or repulsive?

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 electric force always attractive?

The force between the charges is given by Coulomb’s law. The electrostatic force is a very large force. … Like charges repel each other and unlike charges attract each other. Therefore, electrostatic forces are not always attractive.

Why electrostatic force is attractive as well as repulsive in nature?

Like charges repel whereas unlike charges attract each other. For example, the electrostatic force between two positively charged bodies is repulsive while that between a positively charged body and a negatively charged body is attractive in nature.

Why are forces repulsive?

Repulsive force may refer to: A repulsive force of an accelerating universe, which according to certain theories causes planets and matter to get farther and farther apart. Like charges repelling according to Coulomb’s law. Repulsive force (magnetism) between magnets of opposite orientation.

What is the electric force attractive?

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. Coulomb’s law is used to calculate the strength of the force between two charges.

Can a positive force be both attractive and repulsive?

If the particles are both positively or negatively charged, the force is repulsive; if they are of opposite charge, it is attractive. … Unlike the gravitational force however, the Coulomb (or electric) force may be either attractive or repulsive, depending on the signs of the charges and .

Can both the electrostatic force and the gravitational force be either attractive or repulsive?

Yes, both the force between charges and the gravitational force between matter can be either attractive or repulsive.

What are the characteristics of electric line of force?

Following are the 3 properties of electric lines of force.

  • The electric lines of force start from a positive charge and ends on a negative charge.
  • The electric lines of force always enter or leave the charged surface normally.
  • Electric lines of force can never intersect each other. Was this answer helpful?

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 the force between two like masses attractive or repulsive?

Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges. The size of the force varies inversely as the square of the distance between the two charges.

What is the repulsive electrostatic force?

The electric force between charged bodies at rest is conventionally called electrostatic force or Coulomb force. … If the charges have the same sign, the electrostatic force between them is repulsive; if they have different signs, the force between them is attractive.

Can electromagnetic force be attractive as well as repulsive?

Electromagnetic force is a special force that affects everything in the universe because it has an infinite-range attractive, like gravity; it is also a repulsive force which acts between charged particles. … If we have a positive and a negative electric charge, it will result in attraction.

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.

Which contact force is both attractive as well as repulsive in nature?

Answer: The correct answer is electrostatic force. Explanation: Contact forces: When there is an interaction between the two bodies and these objects are in contact with each other then the resulting force is contact forces.
