## Homework Statement

Consider fields of 1.4e5 N/C and 2.7 T within a velocity selector. If the charge then exits and encounters a field of 1.4 T and radius of 2.4 mm within the mass spectrometer, what would be the mass to charge ratio of this ion?

## Homework Equations

v = E/B

m = qrB/V[/B]

q = 1.6 x 10 ^-19C

r = 2.4 x 10^-3 m

B = 1.4 T

## The Attempt at a Solution

I got 51851 m/s for v

and my answer came out way off when I plugged it in for m.

I have the answer but when I try to do it myself. I get the wrong answer.
