• A particle of charge $ - 16 \times {10^{ - 18}}$coulomb moving with velocity $10\,\,m{s^{ - 1}}$ along the x-axis enters a region where a magnetic field of induction B is along the y-axis, and an electric field of magnitude ${10^4}\,\,V/m$is along the negative z-axis. If the charged particle continues moving along the x-axis, the magnitude of B is
