4. An alpha particle is moving South at 74.0 km/s through a magnetic field (5.50 1) directed out of the page Determine the magnetic force (in M) on the alpha particle. tenengel 5. Protons pass undeflected through a device which produces perpendicular electric and magnetic fields. The electric field is generated by parallel plates which are 15.0 cm apart and have a voltage of 1.00 MV between them and the perpendicular coils generate a magnetic field of 1.50 T. Determine the speed of the proton beam. 6. In an electric motor, a 165 mm segment of wire lies perpendicular to the 1.10 T magnetic field and has a 4.00 A current running through it. Determine the magnetic force (in M) on the wire. 7. A 50.0 cm length of wire runs East-West and has a mass of 150 g. The wire is suspended in a 0.800 T magnetic field directed from South to North. Determine the magnitude and direction of the electron flow (in A) in the wire. 8. A proton traveling at 0.960c enters a perpendicular 5.00 T magnetic field directed into the page. Determine the initial radius (in cm) of the electron's path. Direction of Movement 9.
