10.-1 points KnightCP2 24.P.026 My N A mass spectrometer similar to the one in the figure below is designed to separate protain fragments. The fragments are ionized by removing a single electron and then o T uniform magnetic field at a speed of 2.8 x 109 m/s.

Explanation / Answer

10.

Using force balance:

Fc = Fm

m*v^2/r = q*v*B

r = m*v/(q*B)

Using given values:

r = (80*1.67*10^-27)*(2.8*10^5)/(1.6*10^-19*0.80)

r = 0.292 m

Now this distance is radius of circle, So

Diameter = 2*r = 2*0.292 = 0.584 m
