Question

how does the field change if an oppositly charged sheet is placed adjacent to it

Answer 1

Answer:

$The \: electric \: field \: due \: to charge \: plate \: is \: given by \:  E=2ϵ0σ</p><p></p><p>The \: field \: lines \: outside the \: plates \: are \: equal and \: opposite \: so \: the field \: outside \: plates \: will \: be zero. i.e Eout=2ϵ0σ−2ϵ0σ=0</p><p></p><p>The \: field \: in \: between \: the \: plates will \: be \:  Ein=2ϵ0σ+2ϵ0σ=ϵ0σ</p><p></p><p></p><p>$
