Answer:
c. [tex]-5. 65 \times 10^6 N m^2/C.[/tex]
Explanation:
The calculation of the electric flux through the sides of the box is shown below:-
Negative charge in insulating pitch ball, [tex]q = 50\times 10^{-6}[/tex]
[tex]Permittivity = 8.854 \times 10^{-12} F/m[/tex]
Now, we are placing the values into the formula which is here below:-
[tex]Flux = \frac{Negative\ charge}{Permittivity}[/tex]
[tex]= \frac{50\times 10^{-6}}{8.854 \times 10^{-12}}[/tex]
= [tex]-5. 65 \times 10^6 N m^2/C.[/tex]
Therefore we divided the negative charge by permittivity to reach out the electric flux through the sides of the box.
