HOMEWORK for THURSDAY JULY 7, 2005 1. Determine the magnitude and direction of the magnetic force on the following charges in a magnetic field of 0.20 T directed east: (a) A charge 4.0 C moving north at 35 m/s. ;œ  . (b) An electron moving vertically upward at 6000 m/s. 2. Determine the magnitude and direction of magnetic force on a straight wire of length 0.75 m carrying a current of 3.0 A vertically downward in a magnetic field of 0.50 T directed south. 3. The magnetic field at the point A, 10 cm from a current-carrying wire, is 4 10 T and directed upward (out of the plane of the paper). 4 A B (a) In which direction is the current flowing? Mark it on the diagram. (b) What is the magnitude and direction of the magnetic field at point B, 20 cm
