During World War II the isotopes of uranium $235$ ?in uranium $238$ ?had to be separated produced in nuclear bomb separation proceeded used at the time all relied on the difference in the mass of the two nuclei one technique the allies used involved forcing a beam of ions to travel into an ark the strong manic field this is shown to the right question question if the ions are positively charged and they curve in the direction diagram what is the direction of the magnetic field if your random items are all single singly ionized what magnetic field strength is need to cause uranium $235$ ?ions moving at a speed of a $10,000$ ?m$/$s to move a circle with a radius of $1$ ?m if the uranium $235$ ?ions moved in ark with a radius of $2$ ?m what is the radius of the ark in which the uranium $238$ ?ions traveled
