Final Answer:

The electric flux through the shaded surface is Φ = 2π * (2 + 3i) * A, where A is the area of the shaded surface.

Step-by-step explanation:

To find the electric flux through the shaded surface, we first need to find the enclosed charge. Since the charge distribution is a rectangular box with a height of 2 units, a width of 3 units, and a depth of 1 unit, the enclosed charge is given by:

Q = ∫∫∫(ρ(x,y,z) d^3r

where ρ(x,y,z) is the charge density at each point in space. Since the charge density is uniform and given by ρ(x,y,z) = q/V, where V is the volume of the box, we have:

Q = ∫∫∫(q/V d^3r

Since the volume of the box is V = 2 * 3 * 1 = 6, we have:

Q = ∫∫∫(q/6 d^3r

Now, we need to integrate over the entire volume of the box. The integration limits are from 0 to 2 in the x and y directions, and from 0 to 1 in the z direction. Therefore, we have:

Q = ∫0^2 ∫0^2 ∫0^1 (q/6) d^3r

Using the appropriate integration rules, we can simplify the integral to:

Q = 2 * 3 * 1 * q = 6 * q

Next, we need to find the electric flux through the shaded surface. The electric flux is given by the equation:

Φ = ∫∫∫(E * dA)

where E is the electric field at each point in space, and dA is the area element of the surface. Since the electric field is given by:

E = -∇(k)

where k is the charge density, we have:

E = -∇(q/6)

Now, we need to integrate the electric field over the entire surface of the box. The surface of the box has an area of A = 2 * 3 * 1 = 6. Therefore, we have:

Φ = ∫∫∫(E * dA)

= ∫∫∫(-∇(q/6) * dA)

= -∫∫∫(q/6 * dA)

Since the area element dA is given by:

dA = dx * dy * dz

we have:

Φ = -∫∫∫(q/6 * dA)

= -∫0^2 ∫0^2 ∫0^1 (q/6) dx * dy * dz

Using the same integration rules as before, we can simplify the integral to:

Φ = -2 * 3 * 1 * q = -6 * q

Therefore, the electric flux through the shaded surface is Φ = -6 * q.
