Question

. 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 plates C and other two plates,
A magnetic field exists along z-axis. A charged particle of
mass m and charge a 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 througsh a
hole inplate C. If E = mv^2/qa, what will be the speed of the
particle at Q?
