If the potential difference applied to tube is doubled and the separation between the filament and the target is also doubled, the cutoff wavelength

If the potential difference applied to an X-ray tube is doubed while keeping the separation between the filament and the target as same, what will happen to the cutoff wavelength?

If the potential difference V applied to the coolidge tube is doubled, then the cut off wavelength
