Answer
$v=3.34\times10^{-2}\frac{m}{s}$
Work Step by Step
As, Magnetic force is :
$F_{B}=ILB$
and :
F=ma
also
v=at
so solving above we can get:
$v=\frac{F_{B}t}{m}$
putting values:
$v=\frac{(9.13\times 10^{-3})(2.56\times10^{-2})(56.3\times10^{-3})(61.1\times10^{-3})}{24.1\times10^{-3}}$
$v=3.34\times10^{-2}\frac{m}{s}$
