Question

Write some good point about Gravitational force and Electromagnetic force

Answer 1

Gravitational force :-
it is the long range force which arises due to interaction of the gravitational fields of bodies. It is responsible for the attraction between particles of various masses in universe.

♪ Characteristics of Gravitational force :

1) It is always attractive force.
2)It is a mass dependent force.
3)It is charge independent.
4)It obeys inverse square law.
5) It is a long range force and operates upto infinite distance.
6) It is a conservative force.


Electro-magnetic force :-

It is a long range force having moderate strength and♪ acts thought electric and magnetic fields.

♪ Characteristics of Electro-magnetic force

1) It may be attractive or repulsive.
2)It obeys inverse square law.
3)It is mass independent force.
4)It is a long range force.
5)It is a conservative force.
6)It is a function of separation between two bodies and acts along the line of joining.

#characteristic of Gravitational force:

1. Gravitational force is always attractive. For example, earth always attracts us but never repels.

2. It is weakest force in nature.

3. It obeys inverse square law. Let us discuss it:
If there are two objects of mass m1 and m2 and they are placed at distance r apart. Then force between them will be:
F = G(m1m2)/r2

4. Gravitational force is a central force.

5. It is a conservative force.

6. They can operate over a very long distances.

7. Graviton is the particle exchanged when the two masses attract through gravitational force. This exchanged particle is called graviton.

#characteristic of electromagnetic force....

1.   These forces may be attractive or repulsion like charges repel each other and unlike charges attract each other.

2.   These forces are governed by Coulomb’s laws which are similar to Newton’s law of gravitation.

3.    They obey inverse square law.

4. Electrostatic forces (between two protons) are 1036 times stronger than gravitational forces between them, for any fixed distance.

5. They operate over distance which are not very large.6. They are central forces.

7.   They are also conservative forces.

8.    The field particle of electromagnetic forces is photon which carries no charge and has zero rest mass.
