The Millikan oil drop experiment of 1909 allowed Robert A. Millikan to determine the charge of an electron. In the experiment, an oil drop is suspended between two charged plates by an electric force that equals the gravitational force acting on the 2.07 x 10-14 kg drop.

a) What is the gravitational force on this oil drop?

b) What is the Electric force on the charge?

c) What is the charge on the drop if the electric field is 1.72 x 105 N/C?

d) How many electrons does this make up?

To analyze the experiment used to determine the properties of an electron. In 1909, Robert Millikan performed an experiment involving tiny, charged drops of oil. The drops were charged because they had picked up extra electrons. Millikan was able to measure the charge on each drop in coulombs. Here is an example of what his data may have looked like. Drop Charge (C) A 3.20×10−19 B 4.80×10−19 C 8.00×10−19 D 9.60×10−19 In Millikan's experiment, the charge on each drop of...

In the early 1900s, Robert Millikan used small charged droplets of oil, suspended in an electric field, to make the first quantitative measurements of the electron’s charge. A 0.79-μm-diameter droplet of oil, having a charge of +e, is suspended in midair between two horizontal plates of a parallel-plate capacitor. The upward electric force on the droplet is exactly balanced by the downward force of gravity. The oil has a density of 860 kg/m3, and the capacitor plates are 6.0 mm...

Experiments carried out by Robert Millikan in 1910-1913 determined the charge of an electron. In his experiment, oil droplets are charged when sprayed into a chamber. He then studied the motion of the charged oil droplets in a uniform electric field. He found that the following measured value of charge appeared on the oil droplets: Drop Charge (10-19 C) 1 13.13 2 6.563 3 19.71 4 22.89 5 16.48 6 8.204 7 11.50 8 26.13 9 18.08 What value of...

In Millikan’s oil-drop experiment, one looks at a small oil drop held motionless between two plates. Take the voltage between the plates to be 2033 V, and the plate separation to be 2.00 cm. The oil drop (of density 0.81 g/cm3) has a diameter of 3 x 10-6m. Find the charge on the drop, in terms of electron units. You need to round your answer to the nearest integer.
