A Singly-Charged Ion Enters a Velocity Selector That Has A 0.18

question 124

Short Answer

A singly-charged ion enters a velocity selector that has a $0.18 - T$ magnetic field perpendicular to an electric field of $1.6 \mathrm { kV } / \mathrm { m }$ , with both fields perpendicular to the velocity of the ion. The same magnetic field is then used to deflect the ion into a circular path of radius $12.5 \mathrm {~cm} . \left( e = 1.60 \times 10 ^ { - 19 } \mathrm { C } \right)$
(a) What velocity was selected by the velocity selector?
(b) What was the mass of the ion?
