Electrostatic

Electrostatic Forces  

The electric charge present almost in universe and around us.  Electric charge unknown a long time for humans being when lighting in the sky he try to explain on imaginary interpretation which was unsatisfactory. 

6000 B.C.  Thales discovered lighting effect also happened when we rubbed Amber against fur. Thales was a Greek philosopher. He was born in Miletus in Greek Ionia.

When fur rubbed against amber it gets magical attracting property to pull toward a non metallic material such as straw, feather and paper.  An ‘elektron ‘is Greek word of electron which is in the form of Mysterious power electric.

                After 2000 year of Thales William Gilbert and other scientist experiment with amber and loadstone, after observation they found that the electricity present in the nature. They also differentiate the electric and magnetic attraction by observing the property of different materials.

                Here we are doing simple experiment to understand the lighting phenomena in nature. When we rubbed the glass rod against the fur the glass rod get property of magnetism.  When we move the glass rod near the small piece of paper it gets attracted towards the glass rod. 

Here is another simple experiment with comb. Now brush your hair with comb in dark room, now move the comb near to your thumb. What you observe? A small sparkle! Yes this because the comb gets charged. Now again brush with your hair and move your comb near to small piece of papers it get attracted towards the comb this is because comb is charged and get property of magnetism.

When object receives the property of attraction then it is called charged. Where ebonite rod is different from glass rod because the glass rod has positive charge and ebonite has negative charge. When same charge of material we brought together it get repulsion while opposite charges brought together it gets attraction. Neutral rods get charged when brought close to charged to rod, the other rod again neutral due to effect of electrostatic Induction.

                But Man still not knows about the nature charge, positive charge and negative charge it is observed only using the practical.
