Two large, thin metal plates are parallel and close to each other. On their inner faces, the plates have surface charge densities of opposite signs and of magnitude `17.0 xx 10^(-22) C .m^(-2)` .What is the electric field
between the plate ?

Explanation

`E_(3) = (sigma_(A) -sigma_(B))/( 2in_(0))= ( 2 sigma_(A))/( 2 in_(0))= ( sigma_(A))/(in_(0))= ( 17.0 xx 10^(-22))/( 8.854 xx 10^(-12))`
`= 1.92 xx 10^(-10) N.C^(-1)`
