Which of the following forces are both repulsive and attractive in nature?
Consider the following statements: (a) Gravitational force is always attractive in nature. (b) Gravitational force is always along the line joining two masses.
Which force is repulsive as well as attractive?
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.
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.
Is gravitational force attractive or repulsive or both?
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 .
Is gravitational force attractive or repulsive in nature?
Now, we know that the mass of the objects that is taken into consideration cannot be negative in nature. Hence, the nature of the gravitational force will always be attractive and not repulsive. Thus, we can conclude that gravitational force cannot be repulsive.
Which of the following force is not electromagnetic in nature?
The weight of a body is not electromagnetic in nature. The weight of the body is the Gravitational force acting on it and this force depends on the acceleration due to gravity.
Which of the following forces is always attractive in nature?
(a) Gravitational force is always attractive in nature.
Is magnetic force attractive or repulsive?
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.
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 always attractive while force can be attractive or repulsive?
Most objects are nearly electrically neutral, and so attractive and repulsive Coulomb forces nearly cancel. Gravitational force on a large scale dominates interactions between large objects because it is always attractive, while Coulomb forces tend to cancel.
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?
Examples of this force include: electricity, magnetism, radio waves, microwaves, infrared, visible light, X-rays and gamma rays. Electromagnetism mediates all chemical, biological, electrical and electronic processes.
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.
