Question

Two electric dipoles of dipole moment $2cm$ and $4cm$ respectively are kept inside a cube of side ${}^{\prime }{a}^{\prime }m$. Total electric flux linked with the cube is (in SI units)

• A. $\frac{6}{{\epsilon }_0}$
• B. $\frac{2}{{\epsilon }_0}$
• C. $\frac{4}{{\epsilon }_0}$
• D. none of these

Answer 1

The correct option is D none of these

Since net charge $=0$

$\therefore \varphi =0$

$\therefore$ option $D$ is correct answer.
