Question

I got first part correct but dont know how to solve the other 2 problems

Answer 1

To determine the amount of electrons in a given charge we need to remember that the charge of an electros is:

`e=-1.602*10^(-19)`

coulombs.

Now, if we have a given amount of charge an we want to know how many electrons are in the charge we divide it by the charge in the electron. In this case we have:

`(-1650*10^(-9))/(-1.602*10^(-19))=1.03*10^(13)`

Therefore we have:

`1.03*10^(13)\text{ electrons }`

We know that for each step the worker collects -50nC, this is the same as collecting:

`(-50*10^(-9))/(-1.602*10^(\cdot19))=3.12*10^(11)\text{electrons}`

electrons. Now, that we know this we divide the maximum amount of charge the component can take by the electrons in each step:

`(10^(12))/(3.12*10^(-11))=3.2`

Threfore the worker can take 3 complete steps before touching the component
