Definition of Electrostatics
Electrostatics is the study of charges at rest. It is electricity that does not move from one point to another in the substance in which it is produced.
Types of Charges
Positive charge
A body becomes positively charged if it losses electron. This can be obtained in the Laboratory if glass rod is rubbed with silk and there is a net transfer of surface electrons from glass to the silk. The glass becomes positively charged and the silk becomes negatively charged.
Negative charge
A body is negatively charged if it gains electron. This is obtained by rubbing ebonite rod with fur and there is a transfer of electrons from the atoms of fur to the ebonite rod. The fur becomes positively charged.
