- How far does the electron of a hydrogen atom have to be removed from the nucleus for the force of attraction equal to the weight of the electron at the surface of the earth? PLEASE WRITE NICELY DONT TYPERutherford backscattering spectrometry(RBS) is a technique used to determine the structure and composition ofmaterials. A beam of ions (typically helium ions) is accelerated to highenergy and aimed at a sample. By analyzing the distribution and energyof the ions that are scattered from (that is, deflected by collisions with)the atoms in the sample, researchers can determine the sample’s composition.To accelerate the ions to high energies, a tandem electrostaticaccelerator may be used. In this device, negative ions (He-) start at apotential V = 0 and are accelerated by a high positive voltage at themidpoint of the accelerator. The high voltage produces a constant electricfield in the acceleration tube through which the ions move. Whenaccelerated ions reach the midpoint, the electrons are stripped off, turningthe negative ions into doubly positively charged ions (He++). Thesepositive ions are then repelled from the midpoint by the high positivevoltage there and continue to accelerate to…In tokamaks, strong B fields are necessary for confinement. If a tokamak has a minor radius of 0.6m, and the Deuterium ions are at 200 kev, find out if confinement can be achieved with a 5T field.
