An electron moving with a velocity v$=(4\mathrm{.}0$i$+3\mathrm{.}0$j$+2\mathrm{.}0$k$)106$m$/$sv$=(4\mathrm{.}0$i$^+3\mathrm{.}0$j$^+2\mathrm{.}0$k$^)106$m$/$s enters a region where there is a uniform electric field and a uniform magnetic field. The magnetic field is given by B$=(1\mathrm{.}0$i$2\mathrm{.}0$j$+4\mathrm{.}0$k$)102$T$.$B$=(1\mathrm{.}0$i$^2\mathrm{.}0$j$^+4\mathrm{.}0$k$^)102$T$.$ If the electron travels through a region without being deflected, what is the electric field?
