In different experimental trials, an electron, a proton, or a doubly charged oxygen atom (O--), is fired within a vacuum tube. The particles trajectory carries it through a point where the electric potential is 40.0 V and then through a point at a different potential. Rank each of the following cases according to the change in kinetic energy of the particle over this part of its flight from the largest increase to the largest decrease in kinetic energy. In your ranking, display any cases of equality.
   (a) An electron moves from 40.0 V to 60.0 V.
   (b) An electron moves from 40.0 V to 20.0 V.
   (c) A proton moves from 40.0 V to 20.0 V.
   (d) A proton moves from 40.0 V to 10.0 V.
   (e) An O-- ion moves from 40.0 V to 60.0 V.

  1.a > b > c > e > d
  2.b > a = c > d > e
  3.e > d > a = c > b
  4.c > e > a = b > d

Question 2

The two-lens astronomical telescope constructed for the experiment produces an inverted image of the object. To convert the astronomical telescope to a terrestrial telescope, mount an inverting lens in the system. Determine the position for an inverting lens that will not change the magnification of the telescope.

Answer to Question 2

Place the inverting lens so that the image from the objective lens is at the radius of
curvature of the inverting lens.
