- B.A field that decreases in strength with distance
- C.A field that is constant in all directions
- D.A field with no forces acting
Model answer
What a good answer should say
- A field that decreases in strength with distance
Explanation
Why this works
Radial field-line patterns show that the strength of the field diminishes as the distance from the source increases. This evidence indicates that the force experienced by an object in the field will decrease with distance, implying that such fields are typically associated with point sources like masses or charges.
Thus, radial fields are characterized by decreasing strength with distance.
