In Millikan's experiment, a drop of oil (density ? = 0.925 g/cm3)carries an excess charge of 8 electrons. The magnitude of theelectric field needed to levitate the oil drop is 2.78 x 106 N/C.What is the radius of the oil drop (assumed to be spherical)?

Express the result in the unit [µm] and to three significantfigures. If you must use scientific notation, please enter asfollows: e.g. 0.000123 = 1.23E-4. Only answer in numerical values,no units. For negative numbers, leave no space between the negativesign and the number: e.g. right: -1.00, wrong: - 1.00.
