Discussion Question 3B P212, Week 3 Application of Gauss’ Law Follow the steps outlined on the previous page, find the electric field E at the indicated field point x due to the three charged objects shown below. In all cases, the variable r denotes the distance from the center of the object to the field point. Basic Object #1 : A solid sphere of radius R carrying a volume charge density ρ find E at the indicated field point.
