Question 784: Electrostatics & Capacitance

Question

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

Accepted Answer

Net charges of one dipole $=-e+e=0$
Net charge of 8 dipoles $=8 	imes 0=0$
$\Rightarrow$ Net charge inside cube $=0=q$
By Gauss' law,
Total flux emerging from surface $=\frac{q}{\varepsilon_0}=\frac{0}{\varepsilon_0}=0$

Answer

$\frac{8 e}{\varepsilon_0}$

Answer

$\frac{16 e}{\varepsilon_0}$

Answer

$\frac{e}{\varepsilon_0}$

Answer

zero
