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