Question

Consider an electric field $\vec{E}=E_{0} \hat{x}$, where $E_{0}$ is a constant. The flux through the shaded area (as shown in the figure) due to this field is

• A. $2 E_{0} a^{2}$
• B. $\sqrt{2} E_{0} a^{2}$
• C. $E_{0} a^{2}$
• D. $\frac{E_{0} a^{2}}{\sqrt{2}}$

Answer 1

Answer: (C)

$\left(E_{0}\right)$ (Projected area ) $=E_{0} a^{2}$
