2.4 mole of `H_2` sample was taken . In one experiment ` 60%` of the sample was exposed to conitnuous radiations of frequency ` 4.47 xx 10 Hz`, of which all he electrons are removed from the atom . In another experiment remaining sample was irradiated with light of wavelength ` 600Å` , when all the electrons are removed from the surface , Calculate the ratio of maximum velocity of the ejected electron in the two cases . Also report the velocity of ejected electron in each case . Assume that ejected electrons does not interact wih any photon . (Ionization potential of ` H= 13. 6 eV)`.

Explanation
