6. An ionized helium atom has a mass of 6.6 x 10 kg and a speed of 4.1 x 10 m/s. It moves perpendicular to a 0.77-T magnetic field on a circular path that has a 0.011- m radius. Determine whether the charge of the ionized atom is te or +2e. 7. When beryllium-7 ions (m = 1.165 x 10-26 kg) pass through a mass spectrometer, a uniform magnetic field of 0.3152 T curves their path directly to the center of the detector (see figure below). For the same accelerating potential difference, what magnetic field should be used to send beryllium-10 ions (m = 1.663 x 10-26 kg) to the same location in the detector? Both types of ions are singly ionized (a = +e) T 12. At New York City, the earth's magnetic field has a vertical component of 5.2 x 10% T that points downward (perpendicular to the ground) and a horizontal component of 1.8 x 10%T that points toward geographic north (parallel to the ground). What is the magnitude and direction of the magnetic force on a 24.0 m long, straight wire that carries a current of 35 A perpendicularly out of the ground? magnitude =
