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 = evB evB✔✔ = 2.02e-18 (b) The magnetic force on the electron acts perpendicular O it will affect the electron's speed but not its direction it will affect the electron's direction but not its speed O it will not affect the speed or direction of the electron 2.03e-18 N✔✔ r = (c) The electron will therefore follow a circular circular path. perpendicular✔✔ to the electron's velocity so ... ✔ (2 of 3) Centripetal Motion (d) What is the magnitude of the centripetal force of the electron?
