[SOLVED] using electric force to calculate number of protons
a hydrogen nucleus and a nucleus of an unknown atom are stationary, 5.0x10^-10m apart, the electric charge on the hydrogen nucleus is 1.6x10^-19C.
express the charge you have calculated for the unknown nucleus as a whole number multiple of the charge on the hydrogen nucleus, you may assume this number is the atomic number of the unknown nucleus, ie the number of protons
I used Fe= -ke Q1 Q2 / r^2
my calculation gave me the charge on the unknown nucleus to be -2.39x10^-19C
however, when i try to turn this into some whole number compared to 1.6x10^-19, i either get 1.5 or 0.6, neither of which are whole numbers.
please help with this part of the question, even if its just a nudge as to what on Earth is actually being asked...
neither integers nor any similar work appears in my coursebook and my tutor isn't returning my emails.
please help
