Question

Speed: 3.00x10^5

Uniform magnetic field: .600T directed perpendicularly to the velocity of the ions

Significance of this problem: #16: 99% of all uranium that comes out of the ground (uranium mine) is U40. But it is U235 that is used for nuclear power plants (3-6% O and nuclear weapons (~90% U235). So the concentration of U SS must be increased (enriched). The concentration of U235 is what must be tested by inspectors when they go to a suspected location in North Korea, or fran, or.... 7 enizavp = (axv)p = 16) To select the velocity v = 3 x 105 m/s, F, = Fg. Particles with 5 faster (or slower) speeds will be deflected to the left (or right), 0.1+ = Only particles with the desired speed will go straight through.x 0.1- = This is why it is called a velocity selector. a) What is the field needed to select the velocity given?:noidom 16ubi b) For U235 which has mass m = 235 amu (atomic mass units), what is the mass in kg? c) Find the radius and diameter of the path of the yo tong lug bosh dpi d) Find the mass for a 1238 atom. e) Find the radius and diameter of the path of the 1238 Yoncols bror trei f) What is the distance between where the different ions hit.
