Accepted Answer

For an infinite charged plane
$E = {\sigma  \over {2{\varepsilon _0}}}$ for any value of l
$ \Rightarrow {E_1} = {E_2} = {\sigma  \over {2{\varepsilon _0}}}$

Answer

${E_1} = \sigma /{\varepsilon _0},\,{E_2} = \sigma /2{\varepsilon _0}$

Answer

${E_1} = 2\sigma /{\varepsilon _0},\,{E_2} = \sigma /{\varepsilon _0}$

Answer

${E_1} = {E_2} = \sigma /2{\varepsilon _0}$

Answer

${E_1} = {E_2} = \sigma /{\varepsilon _0}$
