in a region of space electric charge in uniformly distributed throughout the volume. A cube of edge length l is placed in the region and electric flux from the entire surface of the cube is found to be Φ. If a cube of edge length 3l is placed to that region, the electric flux from the surface of the cube will be

Detailed Solution
If Φ be the charge enclosed by the cube of edge length l, then Q = ρl3 where p is the change density.∴ϕ'=Q∈0=ρ∈0l3 ∴ϕ'=Q'∈0=ρ(3l)3∈0=27.ϕ
