Physics · Electrostatic Potential

Inside a uniformly polarised dielectric slab, the net charge in any macroscopic volume element \( \Delta v \) is zero because:

1. A
   dipoles are completely destroyed by the external field
2. B
   the molecules become completely non-polar inside the volume
3. C
   free electrons move freely to cancel any internal field
4. D
   the positive end of each dipole sits close to the negative end of the adjacent dipole
