Question

Q.29 :A chemist in a galaxy far, far away performed the Millikan oil drop experiment and got thefollowing results for the charge on various drops. What is the charge of the electron in zirkombs?
2.56 x 10^-12 zirkombs 7.68 x 10^-12 zirkombs
3.84x 10^-12 zirkombs 6.43 x 10^-13 zirkombs

Short answer

Answer

The charge of the electron in zirkombs is 6.43 x 10^-13 zirkombs

Step-by-step solution

Step-by-Step SolutionStep 1: Chemists results in a galaxy

Oil drop changes are the multiples of whole numbers in charge of an electron. The chemist results in the galaxy are listed above. The smallest results out of these are 6.43 x 10^-13 zirkombs.

Checking the multiple with smallest result

On checking the multiples of this smallest result:

$$\begin{gathered} \frac{2.56\times {10}^{12}}{6.4\times {10}^{-13}}=4 \\ \frac{3.84\times {10}^{12}}{6.4\times {10}^{-13}}=6 \\ \frac{7.68\times {10}^{12}}{6.4\times {10}^{-13}}=12 \end{gathered}$$

Interpretation of the multiples

These three results multiples can be electron’s charge, and it is the whole multiple of electron charge of electrons. The charge of the electron in zirkombs is 6.43 x 10^-13 zirkombs.
