The binding energy of the innermost electron in tungsten is 40 keV. To produce characteristic X-rays using a tungsten target in X-ray tube, the potential difference V between the cathode and anticathode should be: - [A]. V < 40 kV [B]. V<=40 kV [C]. V > 40 kV [D]. V >= 40 kV

D.. V>=40 kV ..... if V is less than 40 eV, t wont b able to knock off the electron from the atom's influence completely...
