I can understand that if there is no charge inside an object then the electric FLUX is zero. Meaning the net integral of field vectors with respect to the area will be zero. But that doesn't mean there are no field lines inside the object at all! does it? I thought it just meant that the number of field lines going in equals the number of field lines coming out. But my lecturer drew it as if the field lines were instantly cut off when in in contact with the surface. Please explain this.
