Question

A piece of purple plastic is charged with 8.45 × 10^6 extra electrons compared to its neutral state. What is its net electric charge (including its sign) in coulombs.

Answer 1

The net electric charge is
`-1.352*10^(-12)\ C`

Step-by-step explanation:

Given that,

No of electron
`n=8.45*10^(6)`

We need to calculate the net electric charge in coulombs

Using formula of net electric charge

Net electric charge = number of electron X charge of one electron

`Q=ne`

Put the value into the formula

`Q=8.45*10^(6)*(-1.6*10^(-19))`

`Q=-1.352*10^(-12)\ C`

Hence, The net electric charge is
`-1.352*10^(-12)\ C`
