Chapter 22.2, Problem 22.2TYU

Rank the following surfaces in order from most positive to most negative electric flux: (i) a flat rectangular surface with vector area $\stackrel{\to }{A}=(6.0m^2)\hat{i}$ in a uniform electric field $\stackrel{\to }{E}=(4.0\text{N/C})\hat{j}$; (ii) a flat circular surface with vector area $\stackrel{\to }{A}=(3.0m^2)\hat{j}$ in a uniform electric field $\stackrel{\to }{E}=(4.0\text{N/C})\hat{i}+(2.0\text{N/C})\hat{j}$; (iii) a flat square surface with vector area $\stackrel{\to }{A}=(3.0m^2)\hat{i}+(7.0{\text{m}}^2)\hat{j}$ in a uniform electric field $\stackrel{\to }{E}=(4.0\text{N/C})\hat{i}-(2.0\text{N/C})\hat{j}$; (iv) a flat oval surface with vector area $\stackrel{\to }{A}=(3.0m^2)\hat{i}-(7.0{\text{m}}^2)\hat{j}$ in a uniform electric field $\stackrel{\to }{E}=(4.0\text{N/C})\hat{i}-(2.0\text{N/C})\hat{j}$.
