The correct answer is: $9.6 \times 10^{-20} \mathrm{C}$
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.
