Q. 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) $\frac{q}{2\varepsilon_{0}}6a^{2}$
Explanation
(b) Eight identical cubes are required to arrange so that this charge is at centre of the cube formed so flux
