A mass spectrometer is used to examine the isotopes of uranium. Ions in the beam emerge from a velocity selector at a speed of 3.00 x 105 m/s and enter a uniform magnetic field of 0.375 T directed perpendicularly to the velocity of the ions. What is the distance between the impact points formed on the photographic plate by ions of 235U and 238U? The mass of a 235U ion is 3.902 x 10-25 kg, and the mass of a 238U ion is 3.952 x 10-25 kg, while both types have a charge of 1.602 x 10-19 C. A mass spectrometer (schematic). Charged particles are first sent through a velocity selector. They then enter a region where a magnetic field B causes positive ions to move in a semicircular path and strike a photographic film at P.
(a) A velocity selector consists of electric and magnetic fields described by the expressions E = Ek and B = Bj, with B = 24.0 mT.

A pellet which holds a charge of 10 coulombs is moving upwards (+Y) and driven by an electric field in the same direction with a magnitude of 50 V/m. There is a magnetic field with a magnitude of 25 Tesla’s pointing downwards (-Y). How fast does the pellet need to be going for the magnetic force to cancel the electric force? Group of answer choices 0.5 m/s 2 m/s 4 m/s The forces will cancel out at any speed the pellet may be travelling In this case, the electric force cannot be canceled out by the magnetic force

A beam of electrons with velocity vx = 5 x105 m/s is introduced into a uniform magnetic field Bz = 30 mTesla. An electric field Ey is applied perpendicular to both the initial velocity and the magnetic field. What value of electric field must be applied to leave the electron beam undeflected?
A proton is moving under the combined influence of an electric field (E = 2569 V/m) and a magnetic field (B = 2.45 T), as shown in the figure. Assuming the proton is moving in the direction shown in the figure with speed 255 m/s at the instant it enters the crossed fields, what is the acceleration of the proton? (units are in m/s^2)

An electron in a TV CRT moves with a speed of 6.00 X 107 m/s,in a direction perpendicular to the Earth’s field, which has a strength of 5.00 X 10-5 T. If this is done between plates separated by 1.00 cm, what is the voltage applied? (Note that TVs are usually surrounded by a ferromagnetic material to shield against external magnetic fields and avoid the need for such a correction.)
