Intro: a solid ball of radius rb has a uniform charge density Ο. part a: what is the magnitude of the electric field e(r) at a distance r> rb from the center of the ball? express your answer in terms of Ο, rb, r, and Ο΅0. part b: what is the magnitude of the electric field e(r) at a distance r express your answer in terms of Ο, rb, r, and Ο΅0. part c: 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? check all that apply. e(0) = 0 e(rb)=0 limrββe(r)=0 the maximum electric field occurs when r=0 the maximum electric field occurs when r=rb the maximum electric field occurs as rββ.
