**volume bounded charge density ( ρv ) = - div ( P )

**surface bounded charge density ( ρs ) = P . n

where P is the polarization vector and n is the unit vector.

**now if the di-electric was originally neutral , should all these bounded charges sum up to zero ?**

( volume bounded charge density ρv + surface bounded charge density ρs = 0 ) ?

( volume bounded charge density ρv + surface bounded charge density ρs = 0 ) ?

and what if the source of the electric field was coming from inside the di-electric ( as for example a free point charge ) would it still be the case ?
