If the electric field strength between the plates is 2.20 x 104 V/m what is the charge on the oil droplet? Express your answer in the format of a.bc x 10-de C b) In a Millikan-type experiment, two horizontal charged plates are 2.5 cm apart. A latex sphere of 1.3 x 10-15 kg...
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...
