Question

Gravitational force is a weak force but still it is considered the most important force. Why?

Answer 1

Hint: The Strong Nuclear Force is a force that holds protons and neutrons together in the nucleus. The Weak Nuclear Force, on the other hand, is in charge of certain nuclei's radioactive decay. The attraction between two masses separated by a certain distance is known as gravitational force. The forces of interaction between two charged particles are known as electromagnetism.

Complete answer:
As we know every particle in the complete universe attracts each and every particle in the universe with the force and that is directly proportional to the product of the two masses and inversely proportional to the square of the distance between them, according to Newton's universal law of gravitation. This force is directed down the line that connects them. The gravitational force is the name given to this attraction force.As per the law:
\[F = \dfrac{{G{m_1}{m_2}}}{{{r^2}}}\]

Earth rotates around the Sun; this is all due to gravitational force. Even though the distance between the Sun and the Earth is quite large, the masses of the Earth and the Sun are also quite large, so the gravitational force is strong enough to keep the earth in fixed orbits around the Sun. The earth orbits because the earth's velocity is perpendicular to the gravitational pull, causing orbital motion to occur. From above all the conclusion we can say that as it is the weakest force but still the most important force.

Note: Although gravity is the weakest of the four basic forces, it is responsible for the majority of the universe's stability. There are three forces other than Strong nuclear force, weak nuclear force, and electromagnetic force. Among these forces, the strongest force in the cosmos is the strong nuclear force.
