The figure belоw shоws а mаss spectrоmeter, in which ions of mаss m and charge q are accelerated from rest through a potential difference V before describing semi-circular paths in a region with a constant magnetic field B⇀{"version":"1.1","math":"B⇀"} (out of the page). They strike a detector a lateral distance x⇀{"version":"1.1","math":"x⇀"} from where they enter the field. a. Derive an expression for x⇀{"version":"1.1","math":"x⇀"} in terms of V , B⇀{"version":"1.1","math":"B⇀"}, m, and q. (5 marks) b. If the spectrometer is used to analyze a gas sample containing singly-ionized CO and O2 ions with V = 1000 V and B = 0.2 T, what values of x will be observed? (C and O have masses of 12 and 16 amu where 1 amu = 1.67×10-27{"version":"1.1","math":"1.67×10-27"} kg). (5 marks)
