How do i work out specific charge?! i thought you didn't have to take the electron mass into consideration? HELPPPP!

i've been working out specific charge by doing (electrons)*1.67x10-19 / (protons+neutrons  * 1.67x10-27)

I thought this was the right way but the answer is different in the marks scheme it looks like that have put accounted for electron mass in the calculations
What am i doing wrong? :S

it depends.....

what do you want to know the specific charge of because sometimes it depends on what you want to know:

  • charge of an element
  • charge in a circuit
