Problem 1 (10 Points) A spherical ball of charge with radius 1m and volume charge density  is placed at the origin, where r is the radial distance from the center of the sphere. Additionally, an infinite line charge that extends in the z direction with charge density 1 nC/m is placed at (0,-2,0). Find the total electric field intensity at P(x,y,z) = (0,0,2) . Assume free space.
