# A high-voltage sense wire in a particle detector is modeled as a thin, infinitely long straight wire carrying a uniform linear charge density \(\lambda = 4.0 \text{ nC/m}\). What is the magnitude of the electric field at a radial distance of \(r = 0.10 \text{ m}\) from the center of the wire?

A high-voltage sense wire in a particle detector is modeled as a thin, infinitely long straight wire carrying a uniform linear charge density \(\lambda = 4.0 \text{ nC/m}\). What is the magnitude of the electric field at a radial distance of \(r = 0.10 \text{ m}\) from the center of the wire?

![A vertical dashed line representing a thin straight wire is centered on the canvas, marked with positive sign symbols along its length. A perpendicular horizontal line segment extends to the right from the wire, ending at a point labeled P. The horizontal segment is labeled r = 0.10 m. An arrow labeled E points horizontally to the right from point P. No other labels, lines, text, or axes appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1785830557-sqeRXT.jpg)
