Question

2. A charge Q is uniformly distributed over a rod of length
1. Consider a hypothetical cube of edge l with the centre
of the cube at one end of the rod. Find the minimum
possible flux of the electric field through the entire
surface of the cube.​

Explanation:

Here, half of the length of the rod outside the cube. From Gauss's law, flux,ϕ=Qen/ϵ0,

Out side cube=l/2,

where Q  en ,

​  

=charge inside the cube= Q/2,

​  thus, flux(ϕ)=Q/2ϵ0.
