CAIE A-Level Physics AS 9.1.2 The Charge on Charge Carriers Is Quantised Questions question 1

[Maximum number: 1]

A spherical oil drop has a radius of 1.2×10−6 m1.2 \times 10^{-6} \mathrm{~m}. The density of the oil is 940 kg m−3940 \mathrm{~kg} \mathrm{~m}^{-3}.

The oil drop is charged. Explain why it is impossible for the magnitude of the charge to be 8.0×10−20C8.0 \times 10^{-20} \mathrm{C}.
