A positively charged particle, having charge q, is accelerated by a potential difference V. This particle moving along the x-axis enters a region where an electric field E exists. The direction of the electric field is along positive y-axis. The electric field exists in the region bounded by the lines x=0 and x=a. Beyond the line x=a (i.e., in the region xgta ), there exists a magnetic field of strength B, directed along the positive y-axis. Find a. at which point does the particle meet the line x=a . b. the pitch of the helix formed after the particle enters the region xgea. (Mass of the particle is m.)
