A particle of mass `2 xx 10^-5 kg` moves horizontally between two horizontal plates of a charged parallel plate capacitor between which there is an electric field of `200 NC^-1` acting upward. A magnetic induction of 2.0 T is applied at right angles to the electric field in a direction normal to both `vec B and vec v.` If g is `9.8 ms^-2` and the charge on the particle is `10^-6 C,` then find the velocity of charge particle so that it continues to move horizontally
