Which of the following forces are both attractive and repulsive?
Unlike gravitational force, magnetic force can be attractive or repulsive in nature.
What kind of force is repulsion and attraction?
magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron.
Which forces can be repulsive?
Force can be defined as an effort that changes the state of motion or shape of an object. It can be a pull or push.
Can a positive force be both attractive and repulsive?
A positive force can be both attractive and repulsive in nature. A negative force implies attractive nature.
Is gravitational force attractive or repulsive?
Gravitational force -an attractive force that exists between all objects with mass; an object with mass attracts another object with mass; the magnitude of the force is directly proportional to the masses of the two objects and inversely proportional to the square of the distance between the two objects.
What are the forces of attraction?
Force of attraction is a force that pulls the body near due to its attraction. … Some of them are magnetic force, electric force, electrostatic force and gravitational force. Gravitational force is very well-identified instance force of attraction as it draws objects towards itself regardless of its distance.
Which force is attractive?
The gravitational force is the only force that is purely attractive. Electricity and magnetism can be repulsive as well. For all three forces, the closer the objects are to each other, the stronger the force of attraction. When the objects are far apart, the force of attraction is weaker.
What is electrostatic force of attraction and repulsion?
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.
What a force can be defined as?
A force is a push or pull upon an object resulting from the object’s interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force.
What are the types of non-contact force?
The three types of non-contact forces are gravitational force, magnetic force, electrostatic and nuclear force.
What is balanced force?
Balanced forces are equal in size and opposite in direction. When forces are balanced, there is no change in motion. … When the forces on an object are equal and in opposite directions, the forces are balanced, and there is no change in motion.
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.
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.
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.
