Homework Statement
An ion of mass m and charge q is accelerated from rest through a voltage of ΔV. It then enters a magnetic field. Determine the mass of the ion in terms of the measurable quantities: q, ΔV, (B^→) , and x.
Homework Equations
The Attempt at a Solution
m = q(B^2)(x^2)/(8ΔV)
this is where i am:
F=ma
F - qV x B
ma =qVB
Ui+Ki=Uf+Kf
Ui=Uf+Kf
Ui-Uf=1/2mv^2
ΔU= 1/2mv^2
ΔVq= 1/2 mv^2
