Pick one lab from the following list: Deflection of Electrons in an Electric Field, RC Circuit, Fine Beam Tube, and Thin Lenses. Answer the following questions, each in a sentence or a short paragraph:
(1) Which lab did you pick?
(2) Suppose you found that your result is off by a factor of 100, or 10000%. What do you think might have gone wrong? Give two possibilities.
(3) Now suppose you corrected your mistake but still found an error of 50%. What do you suppose could be some possible reasons? List two of those.
(4) Name two things that you must be careful about when carrying out this experiment in order to minimize the experimental error.
