An electric field is a vector quantity that describes the strength and direction of the force experienced by a charged particle in the presence of an electric charge.
An electric field is produced by a charged cylinder when there is a concentration of charge on the surface of the cylinder. This creates an imbalance of positive and negative charges, resulting in an electric field that extends outward from the surface of the cylinder.
The electric field from a charged cylinder varies inversely with the radial distance from the surface of the cylinder. As the distance increases, the strength of the electric field decreases.
The formula for calculating the electric field from a charged cylinder at a specific radial distance is E = λ/2πε0r, where E is the electric field, λ is the linear charge density of the cylinder, ε0 is the permittivity of free space, and r is the radial distance.
The direction of the electric field from a charged cylinder is always perpendicular to the surface of the cylinder at any radial distance. However, the direction of the electric field changes from pointing outward at smaller distances to pointing inward at larger distances.
