Answer:

Electric field intensity due to infinite line charge (E) = \sf 9 \times 10^4 \ NC^{-1}9×10

−1

Distance from the line charge (r) = 2 cm = 0.02

To Find:

Linear charge density \sf (\lambda)(λ)

Answer:

Electric field intensity due to a infinite long straight line charge is given as:

\boxed {\bf {E = \dfrac{\lambda}{2\pi \epsilon_0 r}}}

2πϵ

By substituting values we get:

\begin{gathered}\rm \implies \cancel{9} \times {10}^{4} = \dfrac{ \cancel{2} \times \cancel{9} \times {10}^{9} \times \lambda}{ \cancel{2} \times {10}^{ - 2} } \\ \\ \rm \implies {10}^{4} = \frac{ {10}^{9} \times \lambda}{ {10}^{ - 2} } \\ \\ \rm \implies \lambda = {10}^{4 - 2 - 9} \\ \\ \rm \implies \lambda = {10}^{ - 7} \: C {m}^{ - 1}\end{gathered}

\therefore∴ \boxed{\mathfrak{Linear \ charge \ density \ (\lambda) = 10^{-7} \ C/m}}
