1. Take \( e/m \) to be the accepted value of \( 1.76 \times 10^{11} \, \text{C/kg} \). For a plate voltage of 100 volts and a circular beam of radius 3.0 cm, what would you expect the required magnetic field \( B \) to be?Assume that the above magnetic field is produced by two Helmholtz coils, and assume that each coil has 119 turns, a radius of 106 mm, and a separation of 106 mm. What current \( I \) is required to achieve the expected magnetic field?

29. A hydrogen isotope separator contains positively ionized hydrogen H', with isotope of hydrogen, Deuterium D<, and other heavy particles, and the ions were released in a potential difference of 200 Volts. The strong magnetic field of 1.4x10 Tesla (out of the page), bends the ions and Deuterium is collected on separate ionic trap as shown in the figure. (Masses MH1=1.67x10°2/ kg, Mp2=2* MH1, Q(H1, D2) = 1.6x10~19 C) What are the velocities of the Deuterium when exiting the plates, in unit of 105 m/s?

The NOAA Space Weather Scales describe three types of space weather storms: Geomagnetic storms, Solar Radiation storms, and Radio Blackouts. A single large solar event can result in all three types of storms being observed at Earth. Assuming a single solar event causes all three to occur, in what order would we expect to observe the three storms? Choose the correct order from the options below. The storms are listed by arrival time, from first to last. A. First Geomagnetic, then Solar Radiation, then Radio Blackout. B. First Solar Radiation, then Radio Blackout, then Geomagnetic. C. First Radio Blackout, then Geomagnetic, then Solar Radiation. D. First Geomagnetic, then Radio Blackout, then Solar Radiation. E. First Radio Blackout, then Solar Radiation, then Geomagnetic. F. First Solar Radiation, then Geomagnetic, then Radio Blackout.
