How is the space between electric field lines related to strength of field?

Explanation:

The strength of the field is proportional to the closeness of the field lines—more precisely, it is proportional to the number of lines per unit area perpendicular to the lines. The direction of the electric field is tangent to the field line at any point in space.

How do electric field lines indicate the strength of the field?

How do electric field lines indicate the strength of an electric field? the space that surrounds electrically charged particles. The closer you get tp a charge, the stronger it gets. ... The repulsion of the like charges creates a space (Gap X) between their electric fields
