Question
Question: The cyclotron frequencies for a deuteron and an alpha particle are v<sub>d</sub> and v<sub>a</sub>, ...
The cyclotron frequencies for a deuteron and an alpha particle are vd and va, respectively. Then –
A
(a) vd < va
A
(b) vd > va
A
(c) vd = va
A
(d) vd = 2va
Explanation
Solution
(c)
Cyclotron frequency = 
Q ma = 4mp , qa = 2e md = 2mp, qd = e
\ (frequency)a = (frequency)d
