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 $\overrightarrow{E}=-10k^{^}N/C$ and magnetic field $\overrightarrow{B}=-5k^{^}$ tesla are present in the region. The particle enters into the magnetic field at       $(4, 0, 0) m$ with a velocity $50 j^{^} m/s$. The particle starts into a curved path on the plane. If coefficient of friction $\mu = \frac{1}{3}$ between particle and plane, the $(qE = 2mg, g = 10 m/s^2) :$
