Doubts on electric field lines and flux

Q1.Is the number of electric feild lines due to a charge DEFINITE? Q2.If it is infinite, then the electric flux due to a charge should be infinite(flux gives the num. Of elctric feild lines passing through an area)? AND Flux should be equal irrespective of the magnitude of charge. Q3.If it is definite,then it will … Continue reading Doubts on electric field lines and flux
