You have a sample of uranium, which has a mix of uranium-235 atoms and uranium-238 atoms. U-235 atoms each have a mass of 3.90 x10-25 kg, while U-238 atoms each have a mass of 3.95 x10-25 kg. You're going to use a mass spectrometer to separate the atoms based on mass, but before the atoms get to the mass separation phase they are accelerated to high speed and then sent through a velocity selector, which is illustrated below. The picture shows a negatively charged object entering a velocity selector. The velocity selector has two components. First, there is a parallel-plate capacitor that creates a uniform electric field directed down. Second, there is a uniform magnetic field, perpendicular to the velocity of the object (see arrow above), that gives rise to a force on the object opposite in direction to the force from the electric field. Which direction is the magnetic force acting on the particle and which direction is the magnetic field? Select an answer and submit.

The magnetic force points down and the magnetic field is into the screen The magnetic force points down and the magnetic field is out of the screen i The magnetic force points out of the screen and the magnetic field is down j The magnetic force points into the screen and the magnetic field is up Your answer Part (b) Homework Unanswered Due Feb 27th, 12:15 PM The magnetic field in the velocity selector has a magnitude of 0.500 T. When the charged particle enters the velocity selector with a velocity of 2.70 105 m/s to the right, it passes straight through the velocity selector without being deflected because it experiences no net force. Determine the magnitude of the electric field inside the velocity selector. V/m Type your numeric answer and submit Unanswered 5 attempts left Submit The charged particles passing through the velocity selector are U-235 and U-235 atoms that have been -19 singly ionized, so each atom has a charge of -e, where e = 1.60 x 10 C. (Adding an electron changes the mass by a negligible amount.) Assume the atoms have the velocity given in part (b). After leaving the velocity selector they then enter the mass separator, where there is just a uniform magnetic field of the same strength and direction as the magnetic field in the velocity selector. All the atoms enter the mass separator at the same point. The atoms then travel through half a circle, and are then collected. The U- 235 atoms are collected in one container and the U-238 atoms are collected in another container. Part (c) == Homework Unanswered Due Feb 27th, 12:15 PM What is the distance between the U-235 atoms and the U-238 atoms after they have all travelled around half a circle in the mass separator?
