Among the following the charge that does not exist on any type of charged body is
Among the following the charge that does not exist on any type of charged body is
$3.2 \times 10^{-19} \mathrm{C}$
$6.4 \times 10^{-19} \mathrm{C}$
$9.6 \times 10^{-20} \mathrm{C}$
$9.6 \times 10^{-18} \mathrm{C}$
Solution
Charge on any body must be an integral multiple of charge on an electron or proton, i.e., charge is quantized, $\mathrm{Q}=$ ne If $Q=9.6 \times 10^{-20}$
than, $\mathrm{n}=\frac{\mathrm{Q}}{\mathrm{e}}=\frac{9.6 \times 10^{-20}}{1.6 \times 10^{-19}}=0.6$
It is not a number, thus this charge does not exists.
