Answer:
(2) 1.60 times 10^-17 C
Explanation:
The value of one elementary charge is
[tex]1 e = 1.60\cdot 10^{-19} C[/tex]
In this problem, we have 100 elementary charges: to find how many Coulombs it corresponds, we have to set up the following proportion
[tex]1 e: 1.60\cdot 10^{-19}C= 100 e : x[/tex]
And solving for x, we find
[tex]x=\frac{(1.6\cdot 10^{-19}C)(100 e)}{1 e}=1.6\cdot 10^{-17}C[/tex]
So, the correct answer is
(2) 1.60 times 10^-17 C
