Problem

A singly ionized sodium ion (q=+1.6×10−19 Cq=+1.6\times10^{-19}\,\text{C}) moves at 6.0×104 m/s6.0\times10^{4}\,\text{m/s} through a uniform 0.80 T0.80\,\text{T} magnetic field. The ion’s velocity is perpendicular to the field and points due north, while the field points straight up. Calculate the magnitude of the magnetic force on the ion and state its direction.
