(a) Explain the
meaning of the statement ‘electric charge of a body is
quantised’.
(b) Why can one ignore quantisation of electric charge when
dealing with macroscopic i.e., large scale charges?

(a) Electric charge of a body is quantized. This means that
only integral (1, 2, …., n) number of electrons can be
transferred from one body to the other. Charges are not transferred
in fraction. Hence, a body possesses total charge only in integral
multiples of electric charge.
(b) In macroscopic or large scale charges, the charges used
are huge as compared to the magnitude of electric charge. Hence,
quantization of electric charge is of no use on macroscopic scale.
Therefore, it is ignored and it is considered that electric charge is
continuous.
