When visualizing the electric field around a positively charged sphere, what can we infer about the density of the electric field lines in relation to the distance from the sphere?

Near a positively charged sphere the electric field is strongest just outside its surface, so the field lines are packed tightly together there. As you move farther away the lines spread out, indicating the field strength is getting weaker. The spacing between lines grows roughly with the square of the distance from the sphere, so at twice the radius the lines are about one‑quarter as dense as they are at the surface. This pattern shows that the electric field decreases as 1/r², which is why the lines become sparser as you go farther from the sphere.
