There are two types of electric charges positive charges and negative charges. The property which differentiates the two types of charges is
The property which differentiates the two types of charges is called the polarity of charge.
What will happen when we rub a glass rod with silk cloth?
When a glass rod is rubbed with silk cloth then some of the electrons from the glass rod get transferred to silk cloth and thus the glass rod gets positive charge and the silk gets negative charge. No new charge is created in the process of rubbing.
When a person combs his hair, static electricity is sometimes generated by what process?
While combing hair, friction between the comb and the hair results is the transfer of electrons.
Object may acquire and excess of deficiency of charge by
Object can be charged by rubbing. During rubbing some of the free electrons may get transferred from one object to other.
The charge on an electron was calculated by
Charge on an electron was measured by Millikan with the help of the oil drop experiment.
