Question

What are the strongest and weakest forces in nature?

Answer 1

Hint: Force is the interaction between two bodies. Its magnitude is determined by the mass and acceleration of a body. There are four fundamental forces in nature; strong nuclear, weak nuclear, gravity and electromagnetic. They act between different bodies and have different properties.

Complete answer:
Force can be described as a push or a pull of an object. It is the product of mass and acceleration of a body. This means that it causes a body to change its state of motion. Its SI unit is Newton (N).
There are four fundamental forces in nature, they are; strong nuclear, electromagnetic, gravity and weak nuclear forces.
All of these forces have strength as well as a direction. Their strength acting on a body decreases as the distance increases.
The strongest force out of the fundamental forces is the strong nuclear force. It is the force which acts only on the particles within the nucleus; it does not depend on the distance and acts within the nucleus.
The weakest force is the gravity. Gravity is the gravitational force acting between the Earth and all bodies on or near its surface. It varies as the inverse square of distance from the center of the Earth. It is one millionth part of a million strong nuclear force.
Therefore, the strongest force in nature is the strong nuclear force and the weakest force is gravity.

Note:
Electromagnetic force is a force which acts between charged particles, while weak nuclear force is the force exerted by the nucleus on all the elements around it and it depends on the distance. The fundamental forces can be attractive or repulsive in nature, gravity is always attractive.
