10. In a mass spectrometer two ions with identical charge and speed form two different semicircular arcs. Ion A’s arc has a radius of 25.0 cm and ion B’s arc has a radius of 50.0 cm. What can you say about their relative masses:

(a) m m A B = ,

(b) m m A B =2 ,

(c) m m A B = 12

, or

(d) you can’t say anything about their relative masses from this data?
