A particle of mass $1\times {10}^{-26} \mathrm{kg}$ and charge $1.6\times {10}^{-19}\mathrm{C}$ travelling with a velocity $1.28\times {10}^6{ \mathrm{ms}}^{-1}$ along positive X axis enters a region in which a uniform electric field $\overrightarrow{\mathrm{E}}$ and a uniform magnetic field $\overrightarrow{B}$ are present. If $\mathrm{E}=-10.24\times {10}^3\hat{\mathrm{k}}{\mathrm{NC}}^{-1}$ and $\overline{\mathrm{B}}=8\times {10}^2\hat{\mathrm{i}}{\mathrm{Wbm}}^{-2}$, the direction of motion of the particle is
