In millikan's oil drop experiment. What are charges on an electron in zeets? Express answer in two significant figures.
A. 1.40x10^-14
B. 2.80x10^-14
C. 3.15x10^-14
D. 3.50x10^-14
E. 4.90x10^-14
To find the charges on an electron in zeets using Millikan's oil drop experiment, we need to determine the value of electric charge (e) on an oil droplet and the total charge (Q) on that droplet.
Millikan's experiment involved the observation of oil droplets suspended in an electric field. The droplets acquire a charge due to the addition or removal of electrons from them. By carefully measuring the droplet's terminal velocity, Millikan was able to calculate the charge on each droplet.
In this experiment, Millikan observed several droplets and found that the charges were always multiples of a fundamental charge, which is the charge on a single electron (e).
To find the charge on an electron in zeets, we need to find the value of the fundamental charge (e) and express it in zeets.
Looking at the given answer choices, we need to find the option that represents the charge on an electron in zeets.
Given options:
A. 1.40x10^-14
B. 2.80x10^-14
C. 3.15x10^-14
D. 3.50x10^-14
E. 4.90x10^-14
To determine the charge on an electron in zeets, we need to convert the charge to the fundamental charge using the following equation:
Fundamental charge (e) = Total charge (Q) / Number of electrons (n)
From Millikan's experiment, we know that Q is a multiple of e, so the value of Q for a single droplet will be n * e.
Now, if we look at the answer choices, we need to select the option that represents the value of e, which will be equal to Q.
Comparing the given answer choices, we can see that the closest option to the fundamental charge value (e) is:
C. 3.15x10^-14
Therefore, the charges on an electron in zeets is approximately 3.15x10^-14 zeets.
