Which of the following is correct regarding electric lines of force ?
(i) Electric lines of force diverge from `+ve` and converge at a `-ve` charge
(ii) Electric lines of force never cross each other , otherwise there will be two directions of electric field at a point of intersection which is not possible
(iii) Closer are the electric lines of forces , stronger is the field , and further apart lines of force ,weaker is electric field
(iv) The electric lines of forces are parallel for a uniform electric field
