Physics - Magnetism Question with Solution | TestHub

A charge particle of mass m and charge q is projected on a rough horizontal XY plane. Both electric and magnetic fields are given by $\overrightarrow{\mathrm{E}}=-10\hat{\mathrm{k}}\mathrm{N}/\mathrm{C}$ and magnetic field $\overrightarrow{\mathrm{B}}=-5\hat{\mathrm{k}}$ T esla are present in the region. The particle enters the magnetic field at ( $4,0,0$ ) m with a velocity $50\hat{\mathrm{J}}\mathrm{m}/\sec$. The particle starts into a curved path on the plane. If coefficient of friction $\mu =\frac{1}{3}$ between particle and plane, then $\left(\mathrm{qE}=2\mathrm{mg},\mathrm{g}=10\mathrm{m}/{\mathrm{s}}^2\right)$.
