Expert Solution

Sources of errors in Milikan's oil drop experiment:

1. Viscosity of air- viscosity depends upon humidity and other factors. It is not possible to determine the value for viscosity accurately.

2. velocity of the oil drop: The eyepiece of the micrometer used to determine the velocity of the oil drop, takes time to focus and give the reading. This may result in small error in calculating the velocity of the drop.

3. selecting only one oil drop: It difficult to select only one oil drop. Also, other oil drops with same charge, behaving in a similar manner may effect the calculations.

4. Electric field: The electric field between the plates may sometimes vary due to fringing effect.

5. Parallax error: There may be some error involved in reading the time and observing the drops.

6. Air pressure: the experiment assumes the air pressure to be constant but practically its not possible. Air pressure, in general, is fluctuating.

Click to launch the animation The Millikan oil drop experiment was a direct and convincing experiment for the measurement of the charge on a single electron. Millikan performed an experiment on a charged oil droplet. By balancing the forces acting on the oil droplet, the charge on a single electron can be calculated. Millikan found that the charge of an oil droplet is always a...

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 2.9 x 10-6m. Find the charge on the drop, in terms of electron units. You need to round your answer to the nearest integer.

Some of Millikan’s oil-drop data are shown below. The measured quantities were not actual charges on oil drops but were proportional to these charges.

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...
