Question

Choose the correct order (decreasing) of the strengths of four fundamental forces of nature?
(A) Electromagnetic force, weak nuclear force, gravitational force, strong nuclear force
(B) Strong nuclear force, weak nuclear force, electromagnetic force, gravitational force
(C) Gravitational force, electromagnetic force, strong nuclear force, weak nuclear force
(D) Strong nuclear force, electromagnetic force, weak nuclear force, gravitational force

Answer 1

Hint: Strong Nuclear force is the force that holds together the fundamental particles to form bigger particles. Gravitational Forces depend on the masses of bodies and distance between their centre of mass. Weak Nuclear force is responsible for the decaying of the particle. Electromagnetic force acts among charged particles. These definitions help us to get the order of the forces.

Complete step by step solution:
Weak nuclear force: Weak nuclear force is also known as weak force. This force is responsible for the decomposition of bodies and particles. This force is also responsible for changing subatomic particles from one type to another. This force plays an important role in various reactions like nuclear fusion that is the source of energy of the sun and hence gives out energy which helps in sustaining the various forms of life on the Earth.
Electromagnetic force: Electromagnetic force is also known as Lorentz force. The force acting among charged particles where “like '' charges repel each other and “unlike” charges attract each other is called the Electromagnetic Force. This force has two components that are, the electric force and the magnetic force. Both these forces are interrelated.
Gravitational force: This is the fundamental force of nature. It is the force of attraction between two bodies having mass or energy. This force helps to hold together every component of galaxy sometimes even galaxies together, but it is the weakest fundamental forces among all others
Strong nuclear force: Strong nuclear force is also known as strong force. This is the strongest fundamental force known in nature. This force helps in holding together the fundamental particles that further forms bigger bodies and particles.

By these definitions we can guess the order of all forces, that is,
Strong nuclear force >electromagnetic force > weak nuclear force > gravitational force

Note: As it is illustrated above the strongest force is stronger than Electromagnetic force then Weak nuclear force and at last Gravitational force. The strongest fundamental force of nature is Strong nuclear force and the weakest fundamental force is Gravitational force.
