Question 1:

An electron with a kinetic energy of 0.7 ke V is fired normal to the lines of a field of magnitude 100 G. Find: a) the radius of its path: m b) its acceleration: c) its period: SAn electron travels at v= 1942000 m/s in a plane perpendicular to a B= 3.1 Tesla magnetic field. Find the radius of the path The radius of the path is equal toHow fast must an electron travel in a B-field of strength B= 0.8 Tesla to travel in a circle of radius r= 0.707 m? The magnetic field is perpendicular to the velocity of the electron. The velocity is equal toA transmission line carries a current of 1.2 X 103 A from west to east. The earth's field is horizontal. points due north. and has a magnitude of 0.5 G. What is the force on 4131 of the wire? DH vertical to the ground
