Final answer:
The correct statements about electric field lines are:
They point away from a positive charge.
They point towards a negative charge.
They never cross.
Step-by-step explanation:
To answer which statements about electric field lines are correct, we must consider several key properties of these lines. Here are the accurate statements aligned with these properties:
- They point away from a positive charge.
- They point toward a negative charge.
- They never cross.
Electric field lines are the visual representations that indicate both the direction and the relative strength of an electric field. Starting from a positive charge and terminating at a negative charge, these lines point in the direction that a positive test charge would move due to the electric field, and their closeness represents the field's strength. Field lines that cross would imply two directions for the electric field at a point, which is not possible, so they never intersect.
