thanks for explaining problem a. I didn't figure it out. :)
regarding 1.0-g:
Suppose a 1.0-g nugget of pure gold has zero net charge. What would be its net charge after it has 1.0% of its electrons removed?
In my understanding, that is in grams, but I wonder why it has negative sign..
Homework Statement
A balloon, initially neutral, is rubbed with fur until it acquires a net charge of -0.60nC. (a) Assuming that only electrons are transferred, were electrons removed from the balloon or added to it? (b) how many electrons were transferred?
Net Charge = Q = -0.60 nCHomework...
