An electron in a cathode ray tube accelerates across a potential dissimilarity 10.0 kv then passes through a small aperture. In one of the electrodes as it emerges on the other side of this electrodevit immediately enters a region in which a uniform magnetic field of width 2.0 cm is present. As the electron reaches the fat edge of the magnetic field its path is deflected 20 degrees from the horizontal direction along which is initially started moving. Decide the velocity, v of the electron and the time elapsed, Δt.
