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:

A carbon-14 ion with a charge of +6.408x10^-19 C and a mass of 2.34x10^-26 kg is sent through a mass spectrometer and hits a detector at a point 10.0 cm to the left of where the beam leaves the velocity selector. The velocity selector and the detector are both in a region of magentic field of strength 0.500 T. What is the speed of the particle after it leaves the velocity selecctor? Then, what is the accelerating potential needed to reach the speed found in that part if the ions start from rest? Please also explain and show the steps you used to get there/the physics behind why/how you got to the answer to help me better understand. Thank you soo much. Also, the work and the explanation or most important because I already have the correct answer - I'm just unsure of how to get there.
In an experiment designed to measure the Earth's magnetic field using the Hall effect, a copper bar 0.430 cm thick is positioned along an east-west direction. Assume n = 8.46 × 1028 electrons/m³ and the plane of the bar is rotated to be perpendicular to the direction of B. If a current of 8.00 A in the conductor results in a Hall voltage of 4.70 x 10-12 V, what is the magnitude of the Earth's magnetic field at this location? μT
