Question

Recall that there are four fundamental forces: the gravitational force, the electromagnetic force, the weak nuclear force, and the strong nuclear force. Select any two of these forces and compare them. Consider their relative strengths, the range of distances over which they operate, and why they are important.

Answer 1

Answer:

The Gravitational force ​force is the force that attracts two bodies toward each other with their masses. We call gravitational force attractive because it always tries to pull masses together, it never pushes them apart.

The Electromagnetic force acts between charged particles and is the combination of all electrical and magnetic forces. For example, the electromagnetic forces holds atoms together in molecules which causes friction, and attracts iron towards the magnet.

The week nuclear force ​​​​​​ is responsible for nuclear beta decay. The weak nuclear forces acts inside individual nucleons. It is the force that allows protons to turn into neutrons and vice versa through beta decay.Beta decay is just one example of the weak nuclear forces.

Strong nuclear forces are the attractive force between protons and neutrons that keeps the nucleus closer together. The strong nuclear force is created between nucleons by the exchange of particles called mesons.

Gravitational force vs the electromagnetic force-

Gravitational force is the weakest force with an infinite range. It has strength of 6 × 10^-39. Where as the electromagnetic force is strongest force and it's relative strength is approximately 10³⁶ times stronger than the earth's gravitational field.

Gravitational force has the longest infinite range of distance over they work because there is no negative mass in Earth's gravity.While electromagnetic forces range of distance over which they operate is infinite. The electromagnetic force is mediated by exchange of photons, which is massless.

Gravitational forces imposes gravity in our universe.Gravity is holding the planets in orbit around the sun and keeps the moon in orbit around Earth. Gravity plays the crucial role in life without gravity we have no atmosphere. Whereas magnetic forces are force exerted by the magnets. Our earth is also surrounded by magnetic fields saves ozone layers from the charged particles .It also protect the Earth's atmosphere from ultraviolet radiations.

Hope this helps!!!
