AbstractStatic electric field in linear uniform neutral dielectric is divergence-free and irrotational. Thus the Maxwell stress tensor is divergence-free as well. So, according to Maxwell, the volume force is ZERO. Only surface forces act on the polarized dielectric. Nevertheless the result contradicts textbook
