Physics 122 Test 4 Monday, Dec 4, 2107 Name Anthong Osod Answer ALL questions Show detailed solution A charge of -8.65 uC Is traveling at a speed of 8.16x 10° m/s in a region of space where there is a magnetic field. The angle between the velocity of the charge and the field is 58.6 A forcef magnitude7.75 x 10 N acts on the charge. Calculate the magnitude of the magnetic field A magnetic field has a magnitude of 0.0017 T, and an electric field has a magnitude of 4.8 x 10 N/C. Both fields point in the same direction. A positive 2.3-pC charge moves at a speed of 3.1x 10fm/s in a direction that is perpendicular to both fields. Determine the magnitude of the net force that acts on the charge. [Note: The two forces are perpendicular to each other. 4.8시 90
