A particle of mass 2 xx 10^(-5) kg moves...

A particle of mass `2 xx 10^(-5)` kg moves horizontally between the plates of a parallel plate capacitor which produce an electric field of `200 N C^(-1)` in the vertically upwards direction. A magnetic induction of 2.0 T is applied at right angles to the electric field in a direction normal to both `vec(E) and vec(v)`. If g is `9.8 m s^(-2)` and the charge on the particle is `10^(-6)C`, then the velocity of the charged particle so that it continues to move horizontally is

A

`2 ms ^(-1)`

B

`20 ms^(-1)`

C
