Solution

To solve the problem, we will use Gauss's law and the relationship between the electric field intensity E \mathbf{E} and volume charge density ρ \rho .

1. ### Break Down the Problem

We need to analyze the divergence of the electric field intensity and how it relates to the volume charge density. This can be described mathematically using Maxwell's equations, specifically Gauss's law.

2. ### Relevant Concepts

According to Gauss's law in differential form, the divergence of the electric field E \mathbf{E} is given by: E=ρε0 \nabla \cdot \mathbf{E} = \frac{\rho}{\varepsilon_0} Where:

  • E \nabla \cdot \mathbf{E} is the divergence of the electric field.
  • ρ \rho is the volume charge density.
  • ε0 \varepsilon_0 is the permittivity of free space.

3. ### Analysis and Detail

From the equation above, we can see that the divergence of the electric field is directly proportional to the volume charge density divided by the permittivity of free space. Thus, it can be explicitly written as: E=ρε0 \nabla \cdot \mathbf{E} = \frac{\rho}{\varepsilon_0}

4. ### Verify and Summarize

Now, we can analyze the options given:

  • a. ε0ρv \varepsilon_0 \rho v
  • b. ρvε0 \frac{\rho v}{\varepsilon_0}
  • c. ε02ρv \varepsilon_0^2 \rho v
  • d. ρvε02 \frac{\rho v}{\varepsilon_0^2}

The correct relationship matches option b: E=ρε0 \nabla \cdot \mathbf{E} = \frac{\rho}{\varepsilon_0}

Final Answer

The divergence of the electric field intensity is equal to: E=ρε0(Option b)ρvε0 \nabla \cdot \mathbf{E} = \frac{\rho}{\varepsilon_0} \quad \text{(Option b)} \quad \frac{\rho v}{\varepsilon_0}
