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. Hence, the correct answer is Option B.
Why is gravitational force not repulsive?
The “gravitational force” is part of a theory of gravity that explains the phenomenon in terms of forces (so you can use Newton’s Laws of motion to make predictions). The force is attractive because the phenomenon is one of “accelerating together”. There is no way a repulsive force describes that.
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.
Which force is both attractive and repulsive in nature?
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.
Is gravitational force a non conservative force?
Gravitational force is an example of a conservative force, while frictional force is an example of a non-conservative force. Other examples of conservative forces are: force in elastic spring, electrostatic force between two electric charges, and magnetic force between two magnetic poles.
Are gravitational interactions always attractive?
B: Types of Interactions. Gravitational forces are always attractive. There is a gravitational force between any two masses, but it is very small except when one or both of the objects have large mass—e.g., Earth and the sun.
Is gravitational force attractive at all distances?
Gravitational force is attractive at all distances. Gravitational force is attractive at small distances and becomes repulsive at large distances.
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.
Can positive force be both attractive and repulsive?
A positive force implies attractive nature. … A positive force can be both attractive and repulsive in nature. A negative force implies attractive nature.
Which force is always repulsive?
Gravitational force can be repulsive. >>Gravitational force can be repulsive.
