a. 0.13 km/s
b. 0.10 km/s
c. 0.16 km/s
d. 0.23 km/s
e. 0.06 km/s

Two single charged ions moving perpendicularly to a uniform magnetic field (B = 0.40 T) with speeds of 5 000 km/s follow circular paths that differ in diameter by 5.0 cm. What is the difference in the mass of these two ions?
a. 2.6 1028 kg
b. 6.4 1028 kg
c. 3.2 1028 kg
d. 5.1 1028 kg
e. 1.1 1028 kg
