Sodium ions (Na*) move at 0.857 m/s through a bloodstream in the arm of a person standing near a large magnet. The magnetic field has a strength of 0.254 T and makes an angle of 46.0° with the motion of the sodium ions. The arm contains 90.0 cm3 of blood with a concentration of 2.00 x 1020 Na* ions per cubic centimeter. If no other ions were present in the arm, what would be the magnetic force on the arm? N

The electric field between the plates of a gear selector in a mass spectrometer is 1×105 V/m. The magnetic field of the speed selector is the same as that of the spectrometer. A beam of +e charged neon ions leaving the speed selector moves in a circular path in the spectrometer before hitting the photographic plate. After a certain time, three spots are observed at distances of 7.4 cm, 7.8 cm and 8.15 cm, respectively.Find the magnetic field assuming that the difference in mass between two isotopes is 1 amu (atomic mass unit):Select the correct answer:
AS0.0-g metal ball having net charge Q = 5.50 µC is thrown out of a window horizontally north at a speed v = 22.0 m/s. The window is at a height h = 18.0 m above the ground. A uniform, horizontal magnetic field of magnitude B = 0.0100 T is perpendicular to the plane of the ball's trajectory and directed toward the west. (a) Assuming the ball follows the same trajectory as it would in the absence of the magnetic field, find the magnetic force acting on the ball just before it hits the ground. (Let the +x-direction be toward the north, the +y-direction be up and the +z-direction be east.) B. (b) Based on the result of part (a), is it justified for three-significant-digit precision to assume the trajectory is unaffected by the magnetic fleld? O Yes O No Explain.
