2013 IPhOO, 4
The Iphoon particle, of charge $q$, is accelerated from rest by a potential difference of $V$. This strange particle then enters a region with a uniform magnetic field, $B$, which is perpendicular to the particle's velocity. The Iphoon follows a circular path with radius $R$. If $ q = 1 \, \mu\text{C} $, $ V = 1 \, \text{kV} $, $ B = 1 \, \text{mT} $, and $ R = 2 \, \text{ft} $, let the weight of an Iphoon, in Newtons, be $ w $. If $ w \approx 10^p $, where $p$ is an integer, find $p$. That is, what is the order of magnitude of the weight?
