Answer:
$E=2.9* 10^3\ N/C$

Step-by-step explanation:

Given

Side of square plate
$L=25\ cm$

distance between plates
$d=5\ mm$

no of electron
$n=10^(11)\ electrons$

electron charge
$e=1.6* 10^(-19)\ C$

$\epsilon _0=8.85* 10^(-12)$

Electric field between plates is given by

$E=(\sigma )/(\epsilon _0)$

$E=((Q)/(A))/(\epsilon _0)$

$E=(ne)/(A\epsilon _0)$

E=(10^(11)* 1.6* 10^(-19))/(0.25^2* 8.85* 10^(-12))

$E=2.9* 10^3\ N/C$
