An electron with mass, m = 9.11 x 10-31 kg, is moving at speed, v = 74 x 105 m/s, perpendicular to the Earth's magnetic field where its strength is B = 1.71 x 10-6 T. SYMBOLIC INPUT. Use the given variables, m, v, and B, along with the fundamental charge, e (as needed). (1 of 3) Magnetic Force (a) Write a symbolic expression for the size of the magnetic force on the moving electron then calculate its numeric value. FB = N (b) The magnetic force on the electron acts [perpendicular to the electron's velocity so ... O it will affect the electron's speed but not its direction O it will affect the electron's direction but not its speed O it will not affect the speed or direction of the electron Submit (c) The electron will therefore follow a ---Select--- --Select--- tangential straight line circular muddy path.
