A chemist in a galaxy far, far away performed the Millikan oil drop experiment and got the following results for the charges on various drops.

2.52 ✕ 10-12 zirkombs 9.45 ✕ 10-12 zirkombs
3.78 ✕ 10-12 zirkombs 6.30 ✕ 10-13 zirkombs
Use these data to calculate the probable charge of the electron in zirkombs.

To calculate the probable charge of the electron in zirkombs, you need to use the Millikan oil drop experiment data and apply the formula developed by Robert Millikan.

The formula is:

q = (9/4) * N * V * g / d

where:
q is the charge of the drop in zirkombs,
N is the viscosity of air (assumed as 1.81 x 10^-5 Pa*s),
V is the volume of the drop,
g is the acceleration due to gravity (9.8 m/s^2),
and d is the distance travelled by the drop.

First, let's find the charges (q) for each drop:

Drop 1: q1 = 2.52 x 10^-12 zirkombs
Drop 2: q2 = 9.45 x 10^-12 zirkombs
Drop 3: q3 = 3.78 x 10^-12 zirkombs
Drop 4: q4 = 6.30 x 10^-13 zirkombs

Now, we can gather the necessary information to calculate the charge of the electron:

- The distance travelled by the drop is the same for all oil drops in the experiment.
- The volume of the drop is unknown and needs to be determined from the data.
- The viscosity of air is known (N = 1.81 x 10^-5 Pa*s).
- The acceleration due to gravity (g) is a constant (9.8 m/s^2).

To calculate the volume of each drop, we can use the following equation:

q = (4/3) * π * r^3 * p

where:
q is the charge of the drop,
r is the radius of the drop,
and p is the density of the oil (ρ = 8.958 g/cm^3).

Rearranging the equation, we get:

r = ((3q) / (4πp))^(1/3)

Now, let's calculate the volume (V) of each drop using the formula above:

V1 = ((3 * q1) / (4 * π * p))^(1/3)
V2 = ((3 * q2) / (4 * π * p))^(1/3)
V3 = ((3 * q3) / (4 * π * p))^(1/3)
V4 = ((3 * q4) / (4 * π * p))^(1/3)

Once we have the volume (V) for each drop, we can calculate the probable charge of the electron using the Millikan oil drop equation:

e = (9/4) * N * V * g / d

where e is the charge of the electron.

Now, you can substitute the values for N, V, g, and d, and calculate the probable charge of the electron (e) in zirkombs.

You know the larger numbers CAN'T be the minimum charge but the smallest number could be. If that actually is the smallest number how many charges would the others have?
