Question

The charge on any negatively charged oil droplet is always a whole-number multiple of the fundamental charge of a single electron.If Millikan was measuring the charge on an oil droplet with 10 negatively charged electrons on it, what charge would he have measured on the droplet?

Answer 1

`1.6* 10^(-18) C`

Step-by-step explanation:

The fundamental charge of a single electron is
`1.6* 10^(-19) C`.

If there are 10 excess electrons, the net charge that would be measured should be 10 times the fundamental charge of a single electron:

`Q=nq_e\\Q= 10* 1.6* 10^(-19) C\\Q= 1.6 * 10^(-18) C`
