Two rectangular plates A and B placed at a distance 2a apart, are connected to a battery to produce an electric field. There are insulators between plantes C and other two plates. A magnetic field exists along z-axis. A charged particle of mass m and charge q passes through a hole at the middle of the plate A with velocity v and strikes at Q which is the middle of the bottom edge of plate B after passing through a hole inplate C. If E= mv2/qa, what will be the speed of the particle at Q?

AB and AC are boundary lines within which a magnetic field B exists. If the magnetic field is absent, a charged particle of mass m and charge q must have passed through a point P on angle bisector of -BAC, at a distance r(2–√) from A, if it has fallen on AB normally at a point Q such that QP =r. If the magnetic field is present, how much time the charged particle will take to come out of the magnetic field
