The collecter of the photocell (in photoelectric experiment ) is made of tugsten while the emitter is Platinum having work function of `10 eV`.Monochromotic radiation of wavelength `124 Å` & power `100 ` watt is incident on emitter which emits photo electrons with a quantum efficiency of `1%`.The accelerating voltage acros the photocell is of `10,000` volts (Use: `hc=12400eV Å`)
If the source of monochromatic radiation of wavelength `124 Å` has an efficiency of `50%`, and the power of `X` ray emitted by the tungsten target is `3W`, the overall efficiency of the apparatus for `X-ray` production is
