At macroscopic level, we deal with charges of order

1 μ C = 1 0^{- 6} C

,
which has

\frac{1 0 ^{- 6}}{1.6 \times 1 0 ^{- 19}} = 0.625 \times 1 0^{13} = 1 0^{13}

charges.
Addition of a few hundred of

e

charges do not make any physically observable effect of attraction repulsion, so quantisation can be ignored.

Q. Statement I At macroscopic level, quantisation of charge has no practical consequence and can be ignored. Statement II −1μC charge contains 1013 times electronic charge e approximately.

Both Statement I and Statement II are correct and Statement II is the correct explanation of Statement I.

Both Statement I and Statement II are correct but Statement II is not the correct explanation of Statement I.

Statement I is correct but Statement II is incorrect.

Statement I is incorrect but Statement II is correct.

At macroscopic level, we deal with charges of order 1μC=10−6C, which has 1.6×10−1910−6​=0.625×1013=1013 charges. Addition of a few hundred of e charges do not make any physically observable effect of attraction repulsion, so quantisation can be ignored.
