Short Answer and/or Sketching (3 points each). 1. Four light rays are incident on a concave mirror, each first passing through the focal point F. Complete the diagram by carefully drawing all four rays in the directions they would propagate after reflecting from the mirror (use a ruler!) (+ II. The figure shown at right depicts the conducting parts of an electroscope (that act as a single, extended, conductor). The electroscope has no net charge (is neutral). A positive charge is brought close to, but not touching the spherical electrode of the electroscope. Draw the charge distribution (using (+) and (-) signs) over the entire electroscope and indicate with arrows if the leaves at the bottom will deflect away or towards one another or use no arrows to indicate they do not deflect.
