There exist uniform magnetic and electric fields of magnitudes 1T and \[1\,V\,{{m}^{-1}}\], respectively, along positive y-axis. A charged particle of mass 1 kg and charge 1 C is having velocity \[1\,\,m\,{{s}^{-1}}\] along x-axis and is at origin at t=0. Then, the coordinates of the particles at time \[\pi s\] will be

• A. \[(0,\,\,1,\,\,2)m\]           
• B. \[(0,\,-{{\pi }^{2}},\,-2)m\]
• C. \[(2,\,{{\pi }^{2}}/2,\,2)m\]     
• D.        \[(0,\,\,{{\pi }^{2}}/2,\,\,2)m\]
