Vedclass · Answer

(c) In the condition of no deflection $\frac{e}{m} = \frac{{{E^2}}}{{2V{B^2}}} $

$\Rightarrow $ If m is increased by $208$ times then $B$ should be increased $\sqrt {208} = 14.4\;$ $times$

In Thomson experiment of finding $e/m$ for electrons, beam of electron is replaced by that of muons (particle with same charge as of electrons but mass $208$ times that of electrons). No deflection condition in this case satisfied if
