For the following diagram, what is the direction of the deflecting force if the particle is: 11. A. B. a fluoride ion. a proton. S N Lesson 2: Moving Charges in Magnetic Fields 12. What is the magnetic field strength if a deflecting force of 0.0010 N is produced on a 7.5 mC particle entering the field at 30 with a speed of 30 m/s? (8.89 mT) 13. 14. 15. What deflecting force is exerted on a charge of 40 C moving at 15 cm/s at 30 to the magnetic field whose flux density is 0.025T? (7.5 x 10 N) What happens to the motion of an electron that is moving in the same direction as (i.e. parallel to) the magnetic field which it enters? What is the deflecting force on an alpha particle moving at 1.0% of the speed of light directly across a magnetic field whose flux density is 0.0030 T? (2.9 10-15 N) CBe-Learn Physics 30 Module 4 Assignment October 2020 16.
