  1. When a positive charge moves from point A to point B in an electric field, the work done W by the electric force is related to the change in electric potential by:
  2. An electron (q = -1.6 times 10^-19 C) moves from a point at 100 V to a point at 50 V. Calculate the work done (in 10^-18 J) by the electric force.
  3. The potential difference Delta V between two points in a uniform electric field vecE can be calculated using:
  4. A uniform electric field has magnitude 500 N/C pointing downward. Calculate the potential difference (in volts) between a point at height h = 0 and a point at height h = 0.20 m.
  5. The electric field vecE is related to the electric potential V by:
  6. Given V(x) = 200 - 50x volts (where x is in meters), the electric field component E_x is:
