How many electrons are missing on the suspended oil drop?

[homevolend]

Homework Statement

A positive charge oil drop weights X N. An electric field intensity of YN/C suspends the drop. How many electrons is the drop missing?

X and Y are given though I don't need to give them because I am wondering what formula to use.,

The Attempt at a Solution

I have already found the charge on the drop as q. now how would I find the amount of missing electrons? I am solving for N I know.


Would I do this: q=Ne?

Thanks

Yes. The number of "missing" electrons is just the (+) charge on the drop divided by the charge on one electron.
