In Milikan's experiment, static electric charge on the oil drops has been obtained by shining $\mathrm{X}$-rays. If the static electric charge on the oil drop is $-1.282 \times 10^{-18} \mathrm{C}$, calculate the number of electrons present on it.

Question

In Milikan's experiment, static electric charge on the oil drops has been obtained by shining $\mathrm{X}$-rays. If the static electric charge on the oil drop is $-1.282 \times 10^{-18} \mathrm{C}$, calculate the number of electrons present on it.,

MARKS App · Accepted Answer

As in Q. 38 above, electrons present $=\frac{-1.282 \times 10^{-18} \mathrm{C}}{-1.6022 \times 10^{-19} \mathrm{C}}=8$
