Q. A point charge $+ q$ is placed at the centre of a cube of side $L.$ The electric flux emerging from the cube is
A) $\frac{q}{\varepsilon_{0}}$
B) Zero
C) $\frac{6qL^{2}}{\varepsilon_{0}}$
D) $\frac{q}{6L^{2}\varepsilon_{0}}$
Explanation
(a) Electric flux coming out through a closed surface is $q/\varepsilon_{0}$
