# Electric Field in a Uniformly Charged Cylinder

When dealing with a uniformly charged cylinder with a uniform charge distribution, it is important to understand how to calculate the electric field at a specific distance from the axis of the cylinder. The formula to determine the electric field in this scenario is quite straightforward and can be expressed as:

## Electric Field Formula for a Uniformly Charged Cylinder

E = (r * ρ) / (2 * ε₀)

where:

E is the electric field,

r is the distance from the axis of the cylinder,

ρ (rho) is the volume charge density, and

ε₀ (epsilon₀) is the permittivity of free space.

This formula takes into account the distribution of charge throughout the volume of the cylinder and allows us to calculate the electric field strength at a specific distance r. By substituting the appropriate values for r, ρ, and ε₀, we can determine the electric field intensity in the given scenario.

Understanding the relationship between the distance from the axis, volume charge density, and permittivity of free space is crucial in solving problems related to electric fields in uniformly charged cylinders. By applying the formula mentioned above, you can analyze and predict the behavior of electric fields in such systems accurately.
