Answer:

$E = 6.77 *10^{3} N/C$

Explanation:

THE GIVEN sheet can be taken as two horizontal force with surface charge density is

at one surface is ∈_1 = $95*10^ {-9} C/mm2$

at oher surface is ∈_2= $-25*10^{-9} C/mm2$

the magnitude of electric field due to surface charge is given as $\frac{∈}{2∈_O}$

So, electric field at P (2 CM below from surface is) = E_1 +E_2

$E = \frac{∈_1}{2∈_O} +\frac{∈_2}{2∈_O}$

$E = \frac{95*10^{-9} +25*10^{-9}}{2*8.85*10^{-12}}$

$E = 6.77 *10^{3} N/C$
