In an experiment for measuring e/m, a cathode particle is passing through two deflecting plates maintained at voltage difference of 40V and separated by a distance of 2cm.The cathode particle traveling at right angles to the field moves in a circular path of radius 2m.Determine the KE of electron in eV.
