Which statement correctly contrasts radial and uniform field patterns?.
- A.Radial fields have constant magnitude; uniform fields have varying magnitude
- B.Radial fields originate from a point; uniform fields have parallel lines
- C.Radial fields are produced by magnets; uniform fields are produced by charges
- D.Radial fields are static; uniform fields are dynamic
Model answer
What a good answer should say
- Radial fields originate from a point; uniform fields have parallel lines
Explanation
Why this works
Define both: Radial fields emanate from a point source; uniform fields consist of straight, parallel lines. Identify key difference: The source geometry – point versus extended – determines whether lines spread out or stay parallel.
Explain when each applies: Point charges or masses produce radial fields; large, evenly distributed sources produce uniform fields. Conclude: The option that states the point source origin versus parallel lines correctly contrasts the two patterns.
