Question 37

Medium

In an experiment to measure the specific charge (the ratio of charge to mass, $qm\displaystyle \frac{q}{m}$ ) of an ion, the ion starts from rest and is accelerated through a potential difference $V$ . It then enters a region of uniform magnetic field of flux density $B\,$ at right angles to its direction of travel, where it moves in a circular path of radius $r$ .

Schematic of the experiment

Which of the following sets of quantities is sufficient to determine the specific charge of this ion?

$V, B$ and $r$

$q, B$ and $r$

$V, m$ and $r$

$V, B$ and $q$
