The discussion focuses on calculating the mass of an atom using a mass spectrometer, specifically for a beam of doubly ionized atoms with given parameters: charge (q = 2(1.60 x 10^-19 C)), magnetic field (B = 5.0 x 10^-2 T), radius (r = 0.120 m), and voltage (V = 3442.9 V). The relevant equation is B²*q*r² / 2*V, which is essential for determining the mass. Participants seek clarification on the formula for path radius in relation to mass (m), charge (q), velocity (v), and magnetic field (B).

Sorry, but I can't tell what the equation you wrote here is supposed to represent.itsmarasilly said:Homework Statement
A mass spectrometer analyzes and gives data for a beam of doubly ionized atoms. The values are q = 2(1.60 x 10^-19 C), B = 5.0 x 10^-2 T, r = 0.120 m, and V = 3442.9 V. Find the mass of one of these atoms.
Homework Equations
B^2*q*r^2 / 2*v
And that equals what?The Attempt at a Solution
(5x10^-2)^2*2(1.6*10^-19)*(0.120)/2(3442.9)
