1. A small droplet of oil with a mass of 2.00 x 10-15 kg is given a small excess charge and is then held suspended in a region of uniform electric field directed upward with a magnitude of 6125 N/C. a) Is the excess charge positive or negative? b) How many elementary charges (unbalanced electrons or protons) are on the oil droplet? Note: this is the famous Millikan Oil Drop Experiment. Millikan took into account the air friction and buoyancy...

Oil Drop 11. Robert Millikan received a Nobel Prize for determining the charge on the electron. To do this, he set up a of oil between potential difference between two horizontal parallel metal plates. He then sprayed drops the plates and adjusted the potential difference until drops of a certain size between the plates, as shown above. Suppose that when the potential difference adjusted until the electric field is 10,000 N/C downward, a certain drop with a mass of remains...
