Question

# A dipole is placed in a shell as shown. Find the electric flux emerging out of the shell and in a hypothetical sphere of radius r as shown.

A
2qε0,0
B
qε0,qε0
C
qε0,qε0
D
0,0

Solution

## The correct option is D $$0, \, 0$$According to the Gauss's law the electric flux  through closed surface is $$\phi=\dfrac{Q_{enclosed}}{\epsilon_0}$$  where $$Q_{enclosed}$$ is the charge inside the closed surface.Here in both cases, $$Q_{enclosed}=+q-q=0$$So the electric flux emerging out of the shell and in a hypothetical sphere of radius r are $$(0,0)$$Physics
