Question

Identify the following force:
1)Force between the charged particles.
2)Attractive for unlike charges and repulsive for like charges.
3)It does not need any intervening medium.
4) It is not the strongest force.

Answer 1

Hint: Electric force and magnetic force requires charged particles. It is attractive for unlike charges and repulsive for like charges. It can travel through a vacuum also, and it is the second most vital force.

Complete step by step answer:
Gravitational force needs an intervening medium and it is the weakest force in all fundamental forces.Strong nuclear force is the strongest nuclear force between all the fundamental forces.Weak nuclear force does not work strongly between charged particles.
Electromagnetic force works between charged particles and it is attractive for unlike charges and repulsive for like charges. It does not need any intervening medium, and it is the second strongest force among the fundamental forces.
Therefore , the option (B) is correct.

Note:Gravity and electromagnetism are just two of the four fundamental forces of nature, specifically two that we can observe every day. The remaining two forces work at the atomic level, which we never feel, despite being made of atoms. The strong force holds the nucleus together. Lastly, the weak force is responsible for radioactive decay, specifically, beta decay where a neutron within the nucleus changes into a proton and an electron, which is ejected from the nucleus. The electromagnetic force is one of the four fundamental forces. Gravity is the attraction between two objects that have mass or energy, whether this is seen in dropping a rock from a bridge, a planet orbiting a star or the moon causing ocean tides. Gravity is probably the most intuitive and familiar of the fundamental forces.
