Question

What is the difference between the strong and weak nuclear forces of the universe?

Answer 1

To solve the given question we will clear our concept regarding the fundamental forces of nature according to their strength and we will also see what will be the difference between the strong and weak nuclear forces of the universe.

Complete answer:
All the forces that we experience in our day to day life can be described by just four fundamental forces of nature:
1. Gravity
2. The weak nuclear force
3. Electromagnetism
4. The strong nuclear force

These four fundamental forces of nature governs everything that happens in the universe.
Gravity is the attraction between two objects that consists of mass or energy. Though gravity holds planets, stars, solar systems and even galaxies together, it turns out to be the weakest of the fundamental forces, especially at the molecular and atomic scales but has infinite range.

The weak nuclear force, also termed as the weak nuclear interaction, is responsible for particle decay. This is the actual change of one type of subatomic particle into another. It is the Next weakest force in nature and short ranged.

The electromagnetic force, also termed as the Lorentz force, acts between charged particles, like negatively charged electrons and positively charged protons. Opposite charges attract each other, while like charges repel one another. The greater the charge, the greater the force is. And much like gravity, this force can be felt from an infinite distance and after the strong nuclear force this is the next strongest force.

The strong nuclear force, also termed as the strong nuclear interaction, is the strongest of the four fundamental forces of nature and is short ranged. It's 6 thousand trillion trillion trillion (that is 39 zeroes after 6!) times stronger than the force of gravity, because it binds the fundamental particles of matter together to form larger particles.

Note: Much like the weak force, the strong force operates only when subatomic particles are extremely near one another. They have to be approximately within ${{10}^{^{-15}}}$ meters from each other, or roughly within the diameter of a proton.
