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.` y. Ifg is `9.8 ms^(-2)` and the charge on the particle is 10 TMC, then find the velocity of charge particle so that it continues to move horizontally.

Options

A. `2 ms^(-1)`
B. `20 ms^(-1)`
C. `0.2 ms^(-1)`
D. `100 ms^(-1)`

Answer

A

Explanation

`2 ms^(-1)`
