(1). A solid ball of radius r has a uniform charge density p.Whatis the magnitude of the electric field E(r) at a distance Rgreater r from the center of the ball? (2).What is the magnitude ofthe electric field E(r) at a distance R less than r from the centerof the earth. Express your answer to question 1 & 2 interms ofp, r, R, and echeleon e. (3) Let represent the electric field dueto the charged ball throughout all of space. Which of the followingstatements about the electric field are true?
Check all that apply.
. E(0) = 0
. E(r) = 0
. Limit as r-infinity E(r) =0
The maximum electric field occurs when r=0
The maximum electric field occurs when r=R
The maximum electric field occurs as r=infinity
