Electromagnetic forces can be either attractive or repulsive. They are long-range forces, which act over extremely large distances, and they nearly cancel for macroscopic objects. (Remember that it is the net external force that is important.)
What type of force is attraction and repulsion?
magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion.
How do you know 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.
Can gravitational force be attractive or repulsive?
Both in the Newton theory of gravitation and in the General Theory of Relativity the gravitational force is exclusively attractive one. However, the quantization of gravity shows that the gravitational forces can also be repulsive .
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 repulsive force in physics?
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 repulsive or attractive?
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.
Why are repulsive forces positive?
You would have learnt this thing in chemistry (In Atom Structure, you would have calculated energy of electrons for different energy levels b/w electron & proton(nucleus)), that attractive force reduces the energy of the electrons and repulsive force increases the energy of electrons) So since energy corresponding to …
Is gravitational force attractive or repulsive class 9?
We all know that all the forces in nature exist in opposites, but gravitational force is the only force that always attracts every object and never reples any.
Is electromagnetic 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.
Why gravitational force is attractive force?
Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.
What is intermolecular force of attraction?
Intermolecular forces are the forces of attraction or repulsion which act between neighboring particles (atoms, molecules, or ions ). These forces are weak compared to the intramolecular forces, such as the covalent or ionic bonds between atoms in a molecule.
How do you find the attractive force?
Calculate the force of attraction according to F = k * q1 * q2 / d2.
