There exists a uniform magnetic and electric field of magnitude $1\, T$ and $1\, V/m$ respectively along positive $y-$ axis. A charged particle of mass $1\,kg$ and of charge $1\, C$ is having velocity $1\, m/sec$ along $x-$ axis and is at origin at $t = 0.$ Then the co-ordinates of particle at time $\pi$ seconds will be :-

  • A

    $(0,1,2)$

  • B

    $(0, - {\pi ^2}/2, - 2)$

  • C

    $(2,  {\pi ^2}/2,  2)$

  • D

    $(0,  {\pi ^2}/2, 2)$
