Which is the most correct statement regarding the drawing of electric field lines?
Electric field lines never cross each other





Electric field lines always connect from one charge to another false because the charges may have the same charge(same sign so no Field line to each other)





Electric field lines always form closed loops false because yo may have two charges of equal magnitude but opposite charge(opposite sign) thus there would be one field line(no loop)





Electric field lines can start on a charge of either polarity false field lines start from positive charges and end on negative charges.
Reply:Electric field lines never cross each other.
