Why is gravity the weakest force?

Hint: In nature, there are four universal or fundamental forces. All stuff in the universe will disintegrate if these forces are not there. Any pull or push that causes an item to change its physical condition is referred to as force (in terms of motion or deformity). A force, according to Newton, is anything that causes an object of mass m to move with an acceleration a. The four fundamental forces of nature are as follows: Strong nuclear force, Weak nuclear force, Gravitational force, Electromagnetic force.

Complete answer:
The weakest of all the forces is gravity. It is the force that determines how much we weigh and how far a basketball goes before returning to the surface when tossed. When two objects are gravitationally locked, their gravitational force is centred at the barycentre of the system, which is not the centre of either item. The scale shows you how much gravity is exerting on your body when you weigh yourself. Our weight was calculated using the formula mass times gravity. Gravitational forces have an impact on both space and time.
One of nature's four basic forces is gravitational force. It's the least effective of the four. It's also the attracting force that results from gravitational interactions. The gravitational force between two bodies is proportional to the product of their masses and inversely proportional to the square of their distance, according to Newton's law of gravity. Gravitational pull is believed to be strong for huge objects, such as the sun or gigantic planets, because their masses are likewise large. This force is considered weak at the atomic level.
\[F{\text{ }} = {\text{ }}\dfrac{{GMm}}{{{R^2}}}\]
The gravitational constant (\[6.67 \times {10^{ - 11}}\]) has a relatively tiny value. As a result, the gravitational pull becomes insignificant. As a result, the gravitational pull is the smallest.

Note:
The gravitational field's intensity is proportional to the acceleration of things affected by it. Falling objects near the Earth's surface accelerate at different rates depending on latitude, surface characteristics such as mountains and ridges, and perhaps abnormally high or low sub-surface density. Under the International System of Units, the International Bureau of Weights and Measures defines a standard gravity value for weights and measures (SI).
