What is electrostatics? Electrostatics stands for static electricity involving study of charges at rest. These charges are developed on insulators when they are rubbed against each other. The charges are produced due to actual transfer of electrons . Quantization and Conservation of charge 1) Quantization of charge a) Electronic charge can exist only as an integral multiple of charge on an electron(-e). b) The possible value of electric charge are q= +1e, -1e, +2e, -2e, +3e, -3e . c) Charge less than the charge on an electron is not possible. 2) Conservation of charge a) On an isolated system, total electric charge always remains constant. b) Total charge on a body is equal to the algebraic sum of all the charges present on it. Every atom is electrically neutral as it contains as many electrons as the number of protons in it. c) When we rub a glass rod with a piece of silk, the positive charge acquire by the glass rod is equal to negative charge acquired by the ...
