What is the net charge of a metal ball if there are 21,749 extra electrons in it?

Explanation:

Given that,

Number of extra electrons, n = 21749

We need to find the net charge on the metal ball. Let Q is the net charge.

We know that the charge on an electron is

To find the net charge if there are n number of extra electrons is :

Q = n × q

So, the net charge on the metal ball is . Hence, this is the required solution.
