In 1909, Millikan performed a famous experiment in which he measured the charge of the electron (and for which he won the Nobel prize). In his experiment, oil drops carrying excess electrons are made to float between two charged large parallel, horizontal plates, as shown, by adjusting a uniform vertical electric field between the plates so that the drops do not fall down. Suppose each drop has a mass of 3.3 × 10−15kg, and one of the drops floats (the...

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 1909, Robert Millikan was the first to find the charge of an electron in his now-famous oil-drop experiment. In that experiment tiny oil drops were sprayed into a uniform electric field between a horizontal pair of oppositely charged plates. The drops were observed with a magnifying eyepiece, and the electric field was adjusted so that the electric force on some negatively charged oil drops was just sufficient to balance their weight. Millikan accurately measured the charges on many oil...

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. In Millikan's experiment, the charge on each drop of oil was measured in coulombs. Imagine the same experiment, but with...

Compute the columbic and gravitational forces between two electrons separated by a distance of: 1 106 meters. The Universal Gravitation Constant is 6.67 10-11 mg/kg/s. The mass of an electron is 9.1 10-31 kg and k= 9 10 NmİC. Form the ratio of Coulomb force to gravitational force, which is bigger?

Millikan measured the electron's charge by observing tiny charged oil drops in an electric field. Each drop had a charge imbalance of only a few electrons. The strength of the electric field was adjusted so that the electric and gravitational forces on a drop would balance and the drop would be suspended in air. In this way the charge on the drop could be calculated. The charge was always found to be a small multiple of 1.6e-19 C. Find the...

In the famous Millikan oil-drop experiment, tiny spherical droplets of oil are sprayed into a uniform vertical electric field. The drops get a very small charge (just a few electrons) due to friction with the atomizer as they are sprayed. The field is adjusted until the drop (which is viewed through a small telescope) is just balanced against gravity and therefore remains stationary. Using the measured value of the electric field, we can calculate the charge on the drop and...
