A thin spherical shell of radius has a total charge uniformly distributed over its surface. Which of the following graphs best represents the variation of magnitude of electric field with distance from the center?
- A. for , and decreases as for Correct answer
- B. increases linearly for , and decreases as for
- C. is constant for , and decreases as for
- D. decreases as for all values of
Solution
For a thin spherical shell, the electric field inside the shell () is zero because no charge encloses a Gaussian surface drawn inside. Outside the shell (), the shell acts as a point charge situated at the center, so , which falls off as .
