`color{blue}✍️` `E` is strong near the charge, so the density of field lines is more near the charge and the lines are closer. Away from the charge, the field gets weaker and the density of field lines is less, resulting in well-separated lines.
`color{blue}✍️` The field lines of a single positive charge are radially outward while those of a single negative charge are radially inward. The field lines around a system of two positive charges (q, q) give a vivid pictorial description of their mutual repulsion, while those around the configuration of two equal and opposite charges (q,–q), a dipole, show clearly the mutual attraction between the charges.
`color{blue}✍️` The field lines follow some important general properties:
`color{blue}{ (i)}` Field lines start from positive charges and end at negative charges. If there is a single charge, they may start or end at infinity.
`color{blue}{(ii)}` In a charge-free region, electric field lines can be taken to be continuous curves without any breaks.
`color{blue}{(iii)}` Two field lines can never cross each other.
`color{blue}{(iv)}` Electrostatic field lines do not form any closed loops.
