Red arrows represent the direction of el. Most books prefer 'field lines' because in the case of magnetism, the field lines don't actually point to where the force takes a charge. (ie by bringing a positive test charge near a positive source charge, the test charge was found to be repelled, thus indicating the direction of the electric field to be radially outward, similarly it was found to be radially inward for the negative source charge); and yes I know that they are just imaginary lines to help us visualise the electric field, I agree that they do not exist; and also you do not need two charges to "view field lines" as field lines represent the electric field and electric field is present around the charge even if there is no other charge near it to experience the force caused by it. Also the electric field lines are perpendicular to the surface of the charges and never intersect each other. Construct an explanation that includes qualitative or quantitative relationships between variables that predict phenomena. The direction of the electric field is tangent to the field line at any point in space.
