Quiz on Electrostatic Fields 2. Consider an infinite line with uniform line charge density Sketch the electric field Pl m with field lines. Quiz on flux of electric fields S₁ S₂/ 3. Consider an infinite sheet in xy plane with uniform surface charge density Ps Sketch the electric field with field lines. A charge q at the center. Two concentric spherical surfaces S₁ and S₂ with radius of R and 2R. Consider the closed surface made of the two northern hemispheres of S₁ and S₂ plus the flat ring shape surface. Find the flux of the field due to q through this closed surface. If the closed surface has the surfaces S₁ shrinks to zero, then it is only S₂. What is the flux of the field through S₂?
