Question

why electric field lines cannot have break in between​

Answer 1

(a) An electrostatic field line is a continuous curve because a charge experiences a continuous force when traced in an electrostatic field. The field line cannot have sudden breaks because the charge moves continuously and does not jump from one point to the other. ... Hence, two field lines never cross each other

Answer 2

The electriic field line cannot have a sudden breaks because the charge moves continuously and does not jump to one point to the other.
