a stample of copper atoms were placed through a mass spectrometer. copper atoms contain two isotopes: 63CU and one other.
a) calculate the velocity of the 63CU if it travels down a 5m flight tube in 4.200 x 10^-6 s
b)the other isotope takes 4.266 x 10^-6 s . calculate the atomic mass of the other isotope. give your answer to the nearest whole number and identify the other isotope.

PLEASE HELP WITH QUESTION B, I KNOW ITS 65 BUT I DONT KNOW HOW TO ACHIEVE THE ANSWER, SHOW WORKING OUT AS WELLL PLSSSS I HAVE A TEST TOMMOROW

So the thing to understand with mass specs is that the Ek (kinetic energy stays the same) therefore Ek(63Cu) = Ek(unknown mass Cu). You can figure out the rest. Let me know if you need another clue
