Question

Common static electricity involves charges ranging from nanocoulombs to microcoulombs. How many electrons must be removed from a neutral object to leave a net charge difference of 0.83μC?

Answer 1

`n=0.5187* 10^(13)` electron must be removed

Step-by-step explanation:

We have given the net charge difference
`q=0.83\mu C=0.83* 10^(-6)C`

We know that charge on one electron
`e=1.6* 10^(-19)C`

Now let n electron are removed to create a charge difference of
`0.83\mu C`

So
`ne=0.83* 10^(-6)`

`n* 1.6* 10^(-19)=0.83* 10^(-6)`

`n=0.5187* 10^(13)` electron must be removed
