In a hypothetical universe, an oil-drop experiment gave the following measurements of charges on oil drops: -3.21×10-19 C, -4.28×10-19 C, -5.35×10-19 C, and -7.49×10-19 C. Assume that the smallest difference in charge equals the unit of negative charge in this universe.

what number goes into 3.21, 4.28, 5.35 and 7.49 more or less evenly? How about -1.07E-19?
-3.21E-19 is 3 of 'em
-4.28E-19 is 4 of 'em
-5.35E-19 is 5 of 'em
-7.49E-19 is 7 of 'em.

The smallest unit of charge is the charge of one electron (or proton), which is 1.602Ã10â19 coulombs.

wild guess....
subtract the number from the preceeding number you'll get..
1.07 x 10^-19 C....i am so sure, but maybe it's negative....
best answer?
