Suppose you use a velocity selector to obtain singly-ionized (missing one electron) isotopes of speed 8.50km/s . The spectrometer is calibrated by where 12C+ arrive after traveling around a semicircle. Suppose the 12C+ ions travel along a semicircle with diameter 22.0cm . Use the actual masses of these ions in your calculations:
1.99×10−26kg for 12C+
2.32×10−26kg for 14N+
2.49×10−26kg for 15N+
Find the separation of the 14N+ and 15N+ isotopes at the detector.

Question

Suppose you use a velocity selector to obtain singly-ionized (missing one electron) isotopes of speed 8.50km/s . The spectrometer is calibrated by where 12C+ arrive after traveling around a semicircle. Suppose the 12C+ ions travel along a semicircle with diameter 22.0cm . Use the actual masses of these ions in your calculations: 
1.99×10−26kg for 12C+ 
2.32×10−26kg for 14N+ 
2.49×10−26kg for 15N+
Find the separation of the 14N+ and 15N+ isotopes at the detector.
