Vedclass · Answer

(A) The charge on any body can be expressed as an integral multiple of the basic unit of charge,i.e.,the charge on one electron. This phenomenon is called the quantization of electric charge.It can be written as $q = \pm ne$,where $n = 1, 2, 3, \dots$.Charge is said to be quantized because it can have only discrete values rather than any arbitrary value. For example,a particle can have a charge of $+10e$ or $-6e$,but not a charge of $3.57e$.From the above discussion,it is clear that electric charge is quantized,which means charge can only exist as an integral multiple of the charge of an electron. Therefore,half of the charge of an electron cannot exist.Hence,both the assertion and the reason are correct,and the reason is the correct explanation of the assertion.

Assertion $(A)$: Half of the charge of an electron does not exist. Reason $(R)$: Electric charge is quantized.
