Conservatios of charge is the propery by virtue of which total charge of an isolated system always remains constant or conserved. For example, when we rub two inslating bodies, A and B, such that n electrons from A transfer to B, then charge acquired by `A = + ne` and charge acquired by `B = -ne`, where e is magnitude of charge on electron. The net charge on isolated system of bodies A and `B =n e -ne - 0`, which was the charge before rubbing. Thus, it is not possible to create or destroy net charge carried by any isolated system. It also imples that charges can be created or destroyed in equal and unlike pairs only.
(i) What is the basic cause of conservation of charge ?
(ii) Name any other fundamental property of electric charge.
(iii) At a time, can you create two like charges of magnitude `q =n e` each ?
(iv) How is the property of conservation of charge reflected in day to day life ?

Explanation

(i) As is known, charging is due to actual transfer of electrons from one day to the other. Assuming that there is no stay loss loss of electrons number of electrons gained by one body is equal to number of electrons lost by the other body. This is the basic cause of conservation of charge.
(ii) Another fundamental of electric charge is 'Quantization of charge'.
(iii) No, as it is against the conservation of charge. Creation of a charge `+q` is accompained by creations of charge `-q`.
(iv) In day to day life, conservation of charge implies that gain of one is always equal to loss of the other. It also imples that sum total of gain in life is equal to sum total of losses in life infact, the sum total of gains and losses in life is constant.
