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