Question

State the 4 basic forces of nature.

Answer 1

Hint: The 4 basic forces of nature are Gravitational force, Electromagnetic force, Strong nuclear force and weak nuclear force. Among the four fundamental forces, gravitational force is the weakest and the strongest force is the strong nuclear force.

Complete step-by-step solution:
There are 4 basic forces of nature. They are Gravitational force, Electromagnetic force, Strong nuclear force and weak nuclear force.
Gravitational force
By virtue of their masses there will be a force of mutual attraction between any two objects is the gravitational force. The force on an object is due to the force due to any other object in the universe. For every object on earth there will be a force of gravity experienced by the body. The motion of a freely falling body , motion of earth, motion of moon etc. are due to the force of gravity.
Electromagnetic force
The force of attraction between the charged particles is called the Electromagnetic force. When the charge is at rest the force is given by the coulomb’s law. The moving charges can produce magnetic fields. The Electromagnetic force travels over large distances without any medium like the gravitational force.
Strong nuclear force
The force which binds the protons and neutrons in a nucleus is called strong nuclear force. The strongest force among the fundamental forces is the strong nuclear force.
Weak nuclear force
The forces that appear in the process such as Beta decay are called the Weak nuclear forces. In the process of Beta decay the end product is an electron and a charge less particle called neutrino.

Note: The Gravitational force operates among all objects in the universe. Weak nuclear force operates among some elementary particles such as electrons and neutrinos. Electromagnetic force operates among charged particles and Strong nuclear force operates among heavier elementary particles.
