If the magnetic field strength in the spectrometer is increased, will the spacing between where the 235u and 238u ions strike increase, decrease, or stay the same?

To answer this item, it must be noted that the magnetic field between two objects is directly proportional to the product of their masses or charges, and inversely proportional to the distance. When the magnetic field between them is increased, the distance between them was also decreased. 

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
