  1. When applying Gauss's Law to find the electric field of an infinite line charge, the best choice for the Gaussian surface is:
  2. An infinite line charge has linear charge density lambda = 3.0 times 10^-9 C/m. Calculate the electric field magnitude (in N/C) at a perpendicular distance of r = 0.20 m from the line. (Use epsilon_0 = 8.85 times 10^-12 C²/(N·m²))
  3. For a uniformly charged non-conducting solid sphere of radius R with total charge Q, the electric field at a point inside the sphere (at radius r < R) is:
  4. For a conductor in electrostatic equilibrium, which statement is TRUE?
