Physics - Magnetism Question with Solution | TestHub

A particle of charge$-16\times {10}^{-18} \mathrm{C}$moving with velocity$10 \mathrm{m} {\mathrm{s}}^{-1}$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${10}^4 \mathrm{V} {\mathrm{m}}^{-1}$is along the negative$z$-axis. If the charged particle continues moving along the$x$-axis, the magnitude of$B$is
