A nonconducting sphere 1.6 m in diameter with its center on thex axis at x = 4 m carries a uniform volume chargeof density Ï = 5.4 µC/m3. Surrounding thesphere is a spherical shell with a diameter of 3.2 m and a uniformsurface charge density σ = -2 µC/m2. Calculatethe magnitude and direction of the electric field at the followinglocations.
(a) x = 4.7 m, y = 0
  N/C î +   N/Cĵ
(b) x = 4 m, y = 1.5 m
  N/C î +   N/Cĵ
(c) x = 2.0 m, y = 3.0 m
  N/C î +   N/Cĵ
(please be careful with b and c last post waswrong
