Question

Eight dipoles of charges of magnitude $e$ are placed inside a cube. The total electric flux coming out of the cube will be

• A. $\frac{8e}{\varepsilon_{0}}$
• B. $\frac{16e}{\varepsilon_{0}}$
• C. $\frac{e}{\varepsilon_{0}}$
• D. Zero

Answer 1

Answer: (D)

Zero

Answer 2

$\varphi = \frac{\Sigma q}{\varepsilon_{0}} = 0$ i.e. net charge on dipole is zero.
