Electromagnetic force

Electromagnetic force is one of the fundamental interaction in universe comprise with electric field and magnetic field. there are three  Fundamental interaction in universe. strong interaction, weak force, electromagnetic force and gravitation. Though, in special theory of relativity there have no explanation about gravitation, but Einstein explained gravitation. In grand unification theorem there have been focussed on unifying all of the fundamental interaction in a one unique continume.

Electrostatic force

Electrostatic force

Electrostatic force means a force between two particles with charge. Two charged particles if with same electric charge excerts a force between themselves is repulsive force. 

The examples of repulsive force between two same particles with positive charge. This types of repulsion is found in repulsion of alpha particles to Nucleus in Rutherfords alpha particle scattering experiment when alpha particles are allowed to pass through the atom.

Two particles with opposite charges attract each other. The force excerts between themselves is attractive force. In atom the attraction between revolving electron with nucleus is attractive force

According to direction of force of electron within Nucleus, electrostatic force are in two types.

Centripetal force that leads electron to collapse with nucleus and directed toward nucleus. Though, electron never collapses with nucleus. This collapsing is restricted by another force with opposite direction is called centrifugal force which is equal to centripetal force This phenomena is also explained in Rutherford's atomic model.

Nucleus

Nucleus is a centre of an atom. It is a positively charged element of an atom. Nucleus consists with positively charged proton and charge nutral neutron. Hence, it belongs positive charge. 

In Rutherford atomic model it termed as positively charged. The entire mass of an atom is concentrated into nucleus. 

How number of proton consists in nucleus same number of negatively charged electron revolves surrounding nucleus. 

When difference of charge between nucleus and electron is found then atom converts into Ion. 

Rapid speed of motion of electron that is revolving surrounding nucleus is not getting displaced or collapsing. This is a result of electrostatic force between electron and nucleus. Two electrostatic force excerts here is called centrifugal force and Centripetal force which are same.

Economica benefit of water hyacinth

Researcher have been started to utilised water hyacinth as a economical purpose instead of considering it as economical burden. At first from Amazonia and brazil water hyacinth spread and now grown as invasive across the world. It have a great impacts on our ecological system. It restrict to sunlight and oxygen to entering into bottom water. Instead of eradication of water hyacinth, utilization may give more beneficial effect. In southern benin a project was undertaken to utilise water hyacinth as economical aspacts. Water hyacinth may convert into fertilizer production. In benin water hyacinth is using to produce biofuel.

Vertebrate population dropped about 60 percent.

Very alarming news of extinction causing in world animals. A large scale of animals are getting extinction due to certain cause. Most of the cause are men maid. The worlds environment is getting unfavorable to survive.

According to WWF, the plannets vertibrates dropped about 60 percent since 1970.
Seabirds are foumd plastic in their stomach.


Freshwater species is declined about 83 percent since 1970.


The major cause of declining of animals from our plannet is water warming, increasing of atmosphere temperature. Rappid industrialisation and unprotective method of discharging of industrial waste.

A destabilized climate can not give people  happy and healthy life.

Electroweak theory



To describe the electromagnetic force and weak force together electroweak theory is emerged. The basic difference of weak force from electromagnetic force is that electromagnetic force acts in large scale where weak force is active in small scale. The distance like a range of atomic Nucleus weak force is found. But electromagnetic force attraction is found in large scale.

Sunlight is an electromagnetic force. It comes from sun from a large distance.
