The ionisation energies of K shell for cobalt copper and molebdenum are 7 8 9 0 and 20 1 keV respectively If any metal out of these is used as in an X ray tube operated at 15kV then target A The K series of characteristic X ray will be emitted by Co only B The K series of characteristic X rays will be emitted by Cu and Co only C The K series of characteristic X rays will be emitted by Cu Co and Mo D The minimum wavelength of continuous X rays emitted by the three metals will not be same 5
