Question

Which of the following is not a fundamental force?
A. Gravitational force
B. Weak nuclear force
C. Strong nuclear force
D. Frictional force
E. Electromagnetic force

Answer 1

Fundamental forces are that govern how objects interact and how certain particles decay. Compare the given options with this statement to find out whether it is a fundamental force or not.

Complete step by step answer:
We know that gravitational force is a force that attracts any two objects which have mass. This force always tries to pull masses together, it never pushes them apart. In fact, every object, including you, me and your family, is pulling on every other object in the entire universe.
Gravitational force is a fundamental force.
Weak nuclear force, also called weak force or weak interaction, a force of nature that underlies some forms of radioactivity, governs the decay of certain nuclei, and initiates the nuclear fusion reaction that fuels the Sun.
Weak nuclear force is also a fundamental force.
Strong nuclear force is a stronger force than weak nuclear force. This force acts between subatomic particles of matter such as protons and neutrons.
Strong nuclear force is also a fundamental force.
Frictional force is a force generated by two surfaces that touch and slide against each other such as bus tire and road. The angle and position of the object affects the frictional force’s volume.
But, frictional force is not a fundamental force.
Electromagnetic force is a force between electrically charged particles. It is the combination between all the electric and magnetic forces. This force can be attractive and repulsive.

Note: There are four fundamental forces in nature. Gravitational, weak nuclear, strong nuclear and electromagnetic forces. They are natural whereas frictional force is artificial.
