Practice Question
The wire has a charge per unit length of and the cylinder has net charge per unit length of \(2 \lambda\)?

Find the electrical field outside the cylinder, a distance r from axis using Gauss’s law if a long & straight wire is surrounded by a hollow metal cylinder whose axis coincides with that of the wire.

Select one correct option:

\(\frac{2\lambda}{2\pi\epsilon_0r}\) radially outward Correct 💪 In-correct 🧐
\(\frac{3\lambda}{2\pi\epsilon_0r}\) radially inward Correct 💪 In-correct 🧐
\(\frac{3\lambda}{2\pi\epsilon_0r} \) radially inward Correct 💪 In-correct 🧐
\(\frac{2\lambda}{2\pi\epsilon_0r}\) radially outward Correct 💪 In-correct 🧐
