A student performed an experiment in an attempt to verify the magnitude of charge on a single metal sphere. The student charged a conducting sphere connected to an insulating stand by putting it in contact with a Van der Graaf generator. The student then contacted the charged, conducting sphere with an identical conducting sphere and then separated them. The student then put one of the conducting sphere apparatuses on a digital scale and zeroed it so that the scale had a reading of 0.00 g. The student then put the ther conducting sphere at different distances from the onducting sphere on the scale and measured the mass reading for each trial. The graph of the student's results is shown below: Note: Gravitational, frictional and edge effecis are negligble and this diagram is not drawn lo scale. 4a) Determine the charge (postive / negative) Plate #2. 4b) Determine the direction of the electric field between Plate #1 and Plate #2. 4c) Determine the magnitude of the electric field between Plate #1 and Plate #2. 4d) Determine the angle, 8, that the electron leaves the region between the parallel plates at. 5) An electron travelling at 6.00 x 10\" m/s [north] enters a 4.00 x 103 T [south] magnetic field.
