11. In a mass spectrometer two ions with identical mass and speed are accelerated 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 net charges:

(a) q q A B = ,

(b) q q A B =2 ,

(c) q q A B = 12

, or

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