Step 1
Electric flux is the measure of the electric field lines passing through a given area. It is proportional to the number of electric field lines going through a surface. The net electric flux through a closed surface is equal to the total charge enclosed by the Show more…

(II) In Fig. $16-61$ , two objects, $O_{1}$ and $O_{2}$ , have charges $+1.0 \mu C$ and $-2.0 \mu C$ , respectively, and a third object, $O_{3},$ is electrically neutral. (a) What is the electric flux through the surface $A_{1}$ that encloses all three objects? (b) What is the electric flux through the surface $A_{2}$ that encloses the third object only?
(II) In Fig. 16-62, two objects, O$_1$ and O$_2$, have charges +1.0$\mu$C and -2.0$\mu$C, respectively, and a third object, O$_3$ is electrically neutral. ($a$) What is the electric flux through the surface $A_1$ that encloses all three objects? ($b$) What is the electric flux through the surface $A_2$ that encloses the third object only?
