Question

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. $\frac{q}{6L^{2}\varepsilon_{0}}$

Answer 1

Answer: (A)

$\frac{q}{\varepsilon_{0}}$

Answer 2

Electric flux coming out through a closed surface is q/ε₀.
