Homework Statement


The three small spheres shown in the figure below carry charges q1 = 4.30 nC, q2 = -7.70 nC, and q3 = 3.40 nC.

Find the net electric flux through each of the following closed surfaces shown in cross section in the figure.

Homework Equations


[itex]\Phi[/itex]E=[itex]\frac{Q_{encl}}{\epsilon_0}[/itex]


The Attempt at a Solution


Using the above equation, I got the right answers for S1 through S4, but I'm getting the wrong answer for S5:
[itex]\Phi[/itex]E=[itex]\frac{Q_{encl}}{\epsilon_0}[/itex]= [itex]\frac{4.30-7.70+3.40}{\epsilon_0}[/itex]= [itex]\frac{0}{\epsilon_0}[/itex]=0
