Question 295 of 311

Find out the surface charge density at the intersection of point $x=3m$ plane and $x$ -axis, in the region of uniform line charge of $8nC{m}^{-1}$ lying along the $z$ -axis in free space.

Show answer and solution

Answer: (A) $0.424nC{m}^{-2}$

\dfrac{2K\lambda }{r}=\dfrac{\sigma }{{\epsilon }_{0}}\left(x=3m\right)

\Rightarrow \sigma =0.424\times {10}^{-9}C{m}^{-2}
