The diagram shows the basic setup for the production of X-rays. `A_(1)` and `A_(2)` are two ammeters, reading `2.55A` and `2.566A` respectively. F is a filament which is alos the cathode. The potential difference applied between P and Q is `50000 V`. Assume that all X-rays photons have the maximum possible energy and that one X-ray photon is emitted for every `100` electron incident on the target. You may assume that the kinetic energy of other electrons reappear as heat in the tube. The number of X-ray photons produced per second is approximatelyA. `10^(12)`B. `10^(15)`C. `10^(18)`D. `10^(21)` |
