An electron is liberated from the lower of the two large parallel metal plates separated by a distance of 20 mm. the upper plate has a potential of `+2400 V` relative to the lower plate. How long does the electron take to reach the upper plate ? Take `(e )/(m)` of electrons `1.8xx10^(11) C kg^(-1)`
