In Millikan's experiment, static electric charge on the oil droplets two obtained by shining `X` rays. If the static electric charges on an oil drople is `-1.282xx10^(-18)C`, the number of electrons captured by the droplet is

A

`8`

B

`6`

C

`7`

D

`5`

Text Solution

Verified by Experts

The correct Answer is:
A
Number of electrons `=("Charge on droplet")/("Charge on one electron")`
`=(-1.282xx10^(-18)C)/(-1.602xx10^(-19)Ce^(-1))`
`=8` electrons
