Consider the mass spectrometer shown schematically in the figure below. The electric field between the plates of the velocity selector is 945 V/m, and the magnetic fields in both the velocity selector and the deflection chamber have magnitudes of 0.900 T. Calculate the radius r of the path for a singly charged ion with mass m = 2.06 x 10-26 kg. mm x x P x Photographic plate Bo.in x Velocity selector x Bi x x + E x x x x x x X x x x x x x x

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 particle passes through a mass spectrometer as illustrated in the figure below. The electric field between the plates of the velocity selector has a magnitude of 8060 V/m, and the magnetic fields in both the velocity selector and the deflection chamber have magnitudes of 0.0920 T. In the deflection chamber the particle strikes a photographic plate 39.6 cm removed from its exit point after traveling in a semicircle. The diagram depicts a velocity selector. The plane of the page is filled with symmetrically arranged crosses labeled vector B0, in above a horizontal plate, and vector Bin below the horizontal plate. Below the horizontal plate, two vertical plates are placed parallel to each other in the right position of the field. The left plate is positively charged and the right plate is negatively charged. The electric field vector E points from the positive plate to the right toward the negative plate. A positively charged particle of charge q and velocity vector v pointing upward…

Two long wires a positioned as shown below -- one along the x direction and one along y direction. Each wire has a current of 10 A in the indicated directions and the top wire is 10 cm above the bottom wire.  What is the angle of the B field exactly half-way between the two wires in degrees?  We define to the right as 0 degrees, up as 90, left as 180, and down as 270. What is the magnitude of the magnetic field in μT to 3 significant digits?
