PHYSICS 6B Ch.20 Worksheet clas.ucsb.edu/staff/vince/ 1) Determine the magnitude and direction of the magnetic force on an electron traveling at a velocity of 3.58x10 6 m/s horizontally to the west in a vertically upward magnetic field of strength 1.30 T. South Direction N 10 4 . 7 ) T 3 . 1 )( 10 58 . 3 )( C 10 6 . 1 ( qvB F 13 s m 6 19 mag = = = = 2) A vertical straight wire carrying an upward 12-A current exerts an attractive force per unit length of 8.8x10 -4 N/m on a second parallel wire 7cm away. What current (magnitude and direction) flows in the second wire? A 7 . 25 I 2 = 3) A rectangular loop of wire is sitting next to a straight wire, as shown. There is a current of 2.5 A in both wires. What is the magnitude and direction of the net force on the loop? ) Attracted ( Upward N 10 9 . 2 F 6 NET = 4) An electron accelerated from rest through a voltage of 410 V enters a region of constant magnetic field. If the electron follows a circular path with a radius of 17cm, what is the magnitude of the magnetic field? use voltage to find KE of electron, then use qvB=mv
