Answer to Question #202433 in Physics for Das

Question #202433

An infinite line carries a linear uniform charge density of 19.6 nC/m). Determine the magnitude of the electric field ( in units of kN/C) at a distance of 5.0 cm from the line.

Expert's answer

"E=\\frac{2\\lambda k}{r}\\\\E=\\frac{2(19.6\\cdot10^{-9})(8.99\\cdot10^{9})}{0.05}=7.0\\frac{kN}{C}"
