If two charges have the same sign, the electrostatic force between them is repulsive; if they have different sign, the force between them is attractive.
Why can the electric force be either 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.
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.
Are electrostatic forces attractive?
The electrostatic force is a very large force. There are two types of charges: positive charges and negative charges. Like charges repel each other and unlike charges attract each other. Therefore, electrostatic forces are not always attractive.
Is electrostatic force always repulsive explain your answer?
Electrostatic force is that force that acts between two charged bodies. … So, the electrostatic force between two positive and negative charges will always be attractive but the electrostatic force between two positive charges and that between two negative charges will always be repulsive.
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.
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.
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.
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.
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 determines whether the electrostatic force between two charged particles is 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.
How does electrostatic attraction work?
Electrostatic forces are non-contact forces; they pull or push on objects without touching them. Rubbing some materials together can result in something called ‘charge’ being moved from one surface to the other. Charged objects pull on other uncharged objects and may either push or pull on other charged objects.
What is electrostatic attraction and repulsion?
Electrostatic Attraction and Repulsion. The attraction and repulsion of electrostatically charged bodies for each other, shown when charged with electricity. If charged with electricity of the same sign they repel each other. If with opposite they attract each other.
What is electrostatic attraction simple?
Electrostatic attraction is essentially the attraction between the positively charged nucleus of an atom and the negatively charged electrons surrounding it.
What determines whether two magnets will be influenced by attractive or repulsive magnetic forces?
It is repulsive if the currents are in opposite directions. Two circular current loops, located one above the other and with their planes parallel, will attract if the currents are in the same directions and will repel if the currents are in opposite directions.
