Question 4 (1 point) Saved Suppose that an ion source in a mass spectrometer produces doubly ionized gold ions, each with a mass of 3.27 x 10-25 kg. The ionsfare accelerated from rest through a potential difference of 0.90 kV. Then, a 0.300-T magnetic field causes the ions to follow a circular path. What is the radius of the path? a. 0.35 m Ob. 0.68 m O c. 0.94 m O d. 0.52 m O e. 0.10 mQuestion 2 (1 point) Saved An electron has a speed of 4. 5 x 10 m / S due east, experiencing a magnetic force that has a maximum magnitude of 8. 0 x 10 14 N and a n direction of due south. What are the magnitude and direction of the magnetic field causing the force? a. 0.4 T pointing up b. 0.2 T pointing down O c. 0.4 T pointing down d. 0.2 T pointing up O e. 0.1 T pointing downQuestion 1 (1 point) Saved W In New England, the horizontal component of the earth's magnetic field has a magnitude of 1. 6 X 10 T. A proton is shot vertically straight down 6 towards the ground with a speed of 2. 1 x 10 m / s. What is the magnitude of the magnetic force? Oa. 1 x 10-18 N Ob. 6 x 10-18 N tion O c. 5 x 10-18 N Od. 7 x 10-18 N Oe. 2 x 10-18 N
