Assignment: Computing Forces in a Magnetic Field Directions: Use the concepts you have learned in this lesson to answer the questions below. Equations F = Bqv F = BIL charge on a proton = 1.6 x 10-19C charge on an electron = -1.6 x 10-19c 1. Find the force on a 115 m long wire at right angles to a 5.0 x 10- N/A . m magnetic field if the current through the wire is 400. A. 2. Find the force on an electron passing through a 0.50 T magnetic field if the velocity of the electron is 4.0 x 10m/s. (answer in scientific notation, include sign) 3. A stream of doubly ionized particles (2 protons) moves at a velocity of 3.0 x 104 m/s perpendicularly to a magnetic field of 0.0900 T. What is the magnitude of the force on the particles? (answer in scientific notation, include sign) 4. A wire 0.50 m long carrying a current of 8.0 A is at right angles to a 1.0 T magnetic field. What force acts on the wire
