Accepted Answer

${1 \over {{C_{eff}}}} = {d \over {K{ \in _0}A}} + {{2d} \over {3K{ \in _0}A}} + {{3d} \over {5K{ \in _0}A}}$
${C_{eff}} = {{15K{\varepsilon _0}A} \over {34d}}$

Answer

${{15} \over {34}}{{K{\varepsilon _0}A} \over d}$

Answer

${{15} \over 6}{{K{\varepsilon _0}A} \over d}$

Answer

${{25} \over 6}{{K{\varepsilon _0}A} \over d}$

Answer

${9 \over 6}{{K{\varepsilon _0}A} \over d}$
