Question

Electric flux lines always extend from a positively charged body to a negatively charged body

Answer 1

For two charges of similar and opposite polarities, the flux distribution appears a shown in below fig.

Fig. Electric Flux distribution (a) Opposite charges; (b) Similar charges

Electic flux lines always extend from a positively (+ve) charged object or body to a negatively ( -ve) charged object or body, from negatively (-ve) charged body to infinity ($\infty$) or from infinty ($\infty$) and to always extend or terminate perpendicular to the charged surfaces, and never corsse each other.

Electric filed lines with at most charge are more dense around body or object.
