Question

How many electrons must be removed from an electrically neutral silver dollar to give it a charge of +3.4 C?

Answer 1

There are
`2.12* 10^(19)\ electrons` that must be removes from an electrically neutral silver dollar.

Step-by-step explanation:

In this case, we need to find the number of electrons must be removes from an electrically neutral silver dollar to give it a charge of +3.4 C. Let n number of electrons removed. It is a case of quantization of electric charge. It is given by :

q = ne

`n=(q)/(e)`

e is the charge on an electron

`n=(3.4\ C)/(1.6* 10^(-19)\ C)`

`n=2.12* 10^(19)\ electrons`

So, there are
`2.12* 10^(19)\ electrons` that must be removes from an electrically neutral silver dollar.
