- A beam of protons is fired into a region of uniform magnetic field with a speed of 80200 m/s. What uniform magnetic field strength, applied perpendicular to the direction of the beam, will deflect the beam into a circular arc with radius of 5.51 mm? T Save for Later Submit Answer12.57×10-7 Tesla is not a valid option of the answers available to choose.The Hall affect is used to measure the carrier density of a thin sheet of electrons. When a current of 80.0 µA flows through the length of the electron sheet, which is 1.2-mm long, 0.27- mm wide and 12-nm thick, a magnetic field perpendicular to the sheet produces a potential difference of 0.53 mV across the width of the sheet. If the carrier density in the electron sheet is 6.74 x 1025 m-3, what is the magnitude of the magnetic field?
- 4. In a hydrogen atom, the electron makes ω = 6×1015 rev/s (recall that this is the angular velocity) around the nucleus. We want to calculate how much current flows through a point in the orbit. (a) Calculate the time period of the orbit. Start by converting ω into rad/s. (b) Use the definition of current to calculate I due to the revolution of the electron around the nucleus.17) How many eV's are created when a frequency of 8.77 e 15 is made from a collapsed electron_ f I be-19A Uranium 235 atom has 92 protons in the nucleus and has a mass of 3.92 E-25 kg. A) How many Uranium atoms would you need to have 1.00 Coulombs of protons? B) What mass of Uranium would that be?
