n is the number of charges of e charge.
e is the fundamental charge on an electron.
solve for n
n= mg/Ee
A small drop of water is suspended motionless in air by a uniform electric field that is directed upward and has a magnitude of 8000 N/C. The mass of the water drop is 3.54 10-9 kg
How many excess electrons or protons reside on the drop?

((3.54 10-9 kg)(9.8))/ 8000 N/C
and it gave me the wrong answer so im not sure what im doing wrong.
