Six identical square plates have surface charge density \(\sigma=1 \mu C/m^2 \). What would be the force of interaction in Newtons between the plates if they are arranged to form a cube (the force acting on one face of the cube). The side of the plates is \(L=10cm\).
Details and assumptions
The vacuum permittivity is \(\epsilon_{0}=8.85\times 10^{-12} F/m \).
