Working on the Millikan Oil Drop experiment:

when working on the lab one of the key challanges was to select proper oil drops. If the oil drops are too large, their uniform falling speeds will be too fast, resulting in more charges carried by these large oil drops resulting in decreased measurement accuracy. QUESTION: why is it the case that the accuracy decreases?

please do your best to answer will rate!!

Animation—The Millikan Oil Drop Experiment Watch the animation to study the Millikan oil drop experiment. 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 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...

Millikan received the 1923 Nobel Prize in Physics for the oil drop experiment that was completed in 1910 about 100 years ago when knowledge of the atomic structure was not clear. (a) what were the two main conclusions of the experiment that were worthy of a Nobel Prize? (b) It has been reported that Millikan “cherry-picked” his experimental data. What are your thoughts on his treatment of the data – did he commit scientific misconduct? (c) Why was oil used...

In a particular Millikan oil-drop apparatus, the plates are 2.25 cm apart. The oil used has a density of 0.815 g/cm3 , and the atomizer that sprays the oil drops produces drops of diameter 1.00×10−3 mm. A) What strength of electric field is needed to hold such a drop stationary against gravity if the drop contains five extra electrons? B) What should be the potential difference across the plates to produce this electric field? C) If another drop of the...

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.

A Millikan-type experiment

Oil has a density of 860kg/m^3. An oil droplet is suspended between two plates 1cm apart by adjusting the potential difference between them to 1177 V. When the voltageis removed, the droplet falls and quickly reaches constant speed. It is timed with a stopwatch and falls 3mm in 7.33 s. The viscosity of air is 1.83*10^-5 kg/(m*s).What is the droplet's charge ?

In Millikan's experiment, the charge on each drop of oil was measured in coulombs. Imagine the same experiment, but with charges measured in a fictitious unit called a zeet (Z). Drop Charge (Z) A 2.55×10−14 B 4.59×10−14 C 5.10×10−14 D 5.61×10−14 E 7.65×10−14 What is the charge on an electron in zeets? Express your answer in zeets using two significant figures.
