What is the magnitude of the electric field

## 4 SOLVED: A solid ball of radius rb has a uniform charge density ρ. What is the magnitude of the electric field E(r) at a distance r>rb from the center of the ball? Let E(r) represent the electric field due to the charged ball throughout all of space. Which of the following statements about the electric field are true? E(0)=0. E(rb)=0. limr→∞E(r)=0. The maximum electric field occurs when r=0. The maximum electric field occurs when r=rb. The maximum electric field occurs as r→∞.
