When electric field lines get closer together, what does that indicate about the electric field? A. The electric field is directly proportional to the density of electric field lines. B The electric field is inversely proportional to the density of electric field lines. The electric field is not related to the density of electric field lines. D The electric field is inversely proportional to the square root of density of electric field lines.

The density of electric field lines is a visual representation of the strength of the electric field. When the field lines are closer together, it indicates a stronger electric field. Therefore, the electric field is directly proportional to the density of electric field lines. This means that as the density of the field lines increases, the strength of the electric field also increases. This is a fundamental concept in the study of electric fields in physics.
