Static Electricity

Questions Worth Pondering

  1. What does it mean when a body is charged? uncharged/neutral?
  2. Do positive charges actually move in the process of charging a body?
  3. In charging a metal conductor by induction (to become positively charged metal conductor), do the positive charges redistribute themselves uniformly over the metal conductor at the end?
  4. How do we determine the direction of the electric field setup by an isolated charge (outward vs inward)?
  5. Lightning is an example of a sudden discharge between the cloud and the earth, what is the direction of the lightning (cloud to earth or earth to cloud)?
  6. Do charges distribute themselves uniformly over the surface of a conductor? (Hint: perfectly spherical vs tear drop shape)
