Electric Field of a Nonuniform Sphere
An insulating sphere with a central cavity has a nonuniform volume charge density given by ρ® = ρ₀e^(-r/a), where ρ₀ and a are positive constants. Which of the following describes the magnitude of the electric field within the insulating material as the distance r from the center increases?
A
Continuously increases
B
Initially increases, then decreases
C
Remains constant
D
