An electron is moving vertically upwards in the uniform magnetic field of the earth . The velocity of the electron is  $2.0\times {10}^6{\mathrm{ms}}^{-1}$ and the horizontal component of earth’s magnetic field is $0.32\times {10}^{-4}\mathrm{tesla}$. Obtain the magnetic and direction of the force on the electron. $[\mathrm{e}=1.6\times {10}^{-19}\mathrm{C}]$
