Answer:
[tex]Q = 1.45 \times 10^{-7} C[/tex]
Explanation:
Here flux passing through each surface is given
so total flux through whole cube is given by
[tex]\phi = 2060 + 1590 + 1690 + 3430 + 1870 + 5760[/tex]
[tex]\phi = 16400 Nm^2 C[/tex]
now we also know that total flux through a closed surface depends on the total charge enclosed in the surface
So we will have
[tex]\frac{Q}{\epsilon_0} = 16400[/tex]
[tex]Q = (8.85 \times 10^{-12})(16400)[/tex]
[tex]Q = 1.45 \times 10^{-7} C[/tex]
