Which charge configuration produces a uniform electric field?
Aa uniformly charged infinite plane sheet
Ba single point charge
Can infinitely long line charge
Da uniformly charged spherical shell
Answer & Solution
Correct answer: A. a uniformly charged infinite plane sheet
1. For an infinite charged plane, $E = \sigma/2\varepsilon_0$, independent of distance from the sheet.
2. A field of constant magnitude and direction everywhere is a **uniform field**, produced by the infinite plane.
3. Point, line and shell charges all give fields that vary with distance.
