Question

What is the flux through a cube of side a if a point charge of q is at one of its corner?

• A. $\frac{2q}{\varepsilon _0}$
• B. $\frac{q}{8\varepsilon _0}$
• C. $\frac{q}{\varepsilon _0}$
• D. $\frac{q}{2\varepsilon _0}6a^2$

Answer 1

Answer: (B)

$\frac{q}{8\varepsilon _0}$

Answer 2

flux $\phi=\frac{ q }{8 \epsilon_{0}}$
