Quantization of Electric Charge

Smallest charge that can exist in nature is (i.e., quanta of charge) the charge of an electron. During friction or rubbing it is only the transfer of electrons which makes the body charged. Hence net charge on any body is an integral multiple of charge of an electron \[[1\centerdot 6\times {{10}^{-19}}C]\] i.e.,

\[q=\pm \,ne\]

where            n = 1, 2, 3, 4,...

Hence no body can have a charge represent as \[2\centerdot 1e,\]

\[2\,.\,5e,\frac{3}{7}\]e etc.

Recently, it has been discovered that elementary particles such as protons or neutrons are composed of more elemental units called quarks.

Which of the following properties is not statisfied by an electric charge?

A) Total charge conservation

B) Quantization of charge

C) Two types of charge

D) Circular line of force
