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