In a hypothetical universe, the charge of the negatively charged zarg was determined via a method similar to Millikan's oil-drop experiment with the following results.

(a) Using the tabulated results, calculate the minimum charge of a zarg.
(b) An additional droplet was determined to have a charge of 3.26 ×10^–15 C. Does this affect the previously calculated charge for a zarg? If yes, calculate the new minimum charge of a zarg.

Identify the unlikely charge of an oil droplet in Millikan's experiment. Use e = 1.6022 × 10^–19 C for the charge of an electron.

Calculate the number of electrons needed to produce a charge of -2.0 C and calculate their mass.

A scientist in a parallel universe performs the Millikan oil-drop experiment. The unit of charge in that universe is gallic (ga). He obtained the following data for four oil droplets (A, B, C, and D):

A 2.06×10^–11 ga
B 2.75×10^–11 ga
C 4.13×10^–11 ga
D 5.50×10^–11 ga

Assuming the four oil droplets are all equal in mass and volume, determine which one would fall most rapidly between the plates.

Consider a hypothetical charge called the york. The charge of each drop was measured in york using the oil drop experiment. Determine the charge of the electron in york (y) and the number of electrons in each drop from the following data gathered:

Oil Drop            # Charge
A                  –2.8 × 10^–8 y
B                  –7.0 × 10^–8 y
C                  –1.26 × 10^–7 y
D                  –9.8 × 10^–8 y

Air conditioning gives shopping malls cold and dry conditions. Static charges may accumulate on the soles of your shoes while you are walking inside the mall. If -25 µC is generated by your body, what is their collective mass?

Calculate the charge-to-mass ratio in C/kg of an alpha particle, ⁴He²⁺, that has a mass of 4.00151 amu.
