Step 1
Electric flux is the measure of the electric field lines passing through a given surface area. It is given by the equation Φ = E.A, where E is the electric field and A is the area. However, in this case, we are given the charges and not the electric field. We Show more…

A cube has sides of length $L=0.300 \mathrm{~m}$. One corner is at the origin (Fig. E22.6). The nonuniform electric field is given by $\overrightarrow{\boldsymbol{E}}=(-5.00 \mathrm{~N} / \mathrm{C} \cdot \mathrm{m}) x \hat{\imath}+(3.00 \mathrm{~N} / \mathrm{C} \cdot \mathrm{m}) z \hat{\boldsymbol{k}} .$ (a) Find the electric flux through each of the six cube faces $S_{1}, S_{2}, S_{3}, S_{4}, S_{5},$ and $S_{6}$. (b) Find the total electric charge inside the cube.
