Two parallel plane sheets 1 and 2 carry uniform charge densities σ 1 and σ 2 as in fig electric field in the region marked II is ( σ 1 > σ 2 ) Options: A . &nbsp−(σ1+σ2)2ϵ0 B . &nbsp−(σ1 σ2)2ϵ0 C . &nbsp(σ1+σ2)2ϵ0 D . &nbsp(σ1−σ2)2ϵ0 E . &nbspIf assertion is false but reason is true.

Answer: Option D : D E = E 1 − E 2 = σ 1 2 ϵ 0 − σ 2 2 ϵ 0 E = σ 1 − σ 2 2 ϵ 0

Two parallel plane sheets 1 and 2 carry uniform charge densities σ1 and σ2 as

Question - Two parallel plane sheets 1 and 2 carry uniform charge densities

σ_{1}

and

σ_{2}

as in fig electric field in the region marked II is (

σ_{1}

σ_{2}

)

Answer: Option D
:
D

E = E_{1} - E_{2}

= \frac{σ_{1}}{2 ϵ_{0}} - \frac{σ_{2}}{2 ϵ_{0}}

E = \frac{σ_{1} - σ_{2}}{2 ϵ_{0}}
