Mass Spectroscopy passage-

It says that doubly ionized isotopes have twice the kinetic energies compared to singly ionized isotopes. Can someone please explain how this is so?

Is it because in 1/2Mv^2= QV, doubly ionized particles have Q=+2 vs. V=+1 in singly ionized particles?

Also, in mass spectroscopy, I thought that usually Z=+1 so that M/Z is virtually like M. I've never seen doubly ionized particles in a mass spectroscopy question before.


Thanks in advance.
