  1. Equipotential surfaces are surfaces where the electric potential has the same value everywhere. Which statement is true?
  2. The equipotential surfaces around a positive point charge are:
  3. For a conductor in electrostatic equilibrium, which statement is FALSE?
  4. A conducting sphere of radius 0.10 m carries total charge +5.0 times 10^-9 C. Calculate the electric potential (in volts) at the surface. (Use k = 9.0 times 10^9 N·m²/C²)
  5. To find the electric potential at a point due to a continuous line of charge with charge density lambda, you must:
