Question
2)A beam of electrons is sent in the positive x-direction in a region with a uniform magnetic field B in the positive y-direction and a uniform electric field E in the positive z-direction. At which of the following speeds would the electrons be deflected in the positive z-direction?v > E/B
v = E/B
v < E/B
3)There is no speed for which this will happen. 3)An ideal solenoid has a field of magnitude 0.10 T when carrying a current of 200 A. The solenoid is 5.0 m long. What is the number of turns for the coils of the solenoid?
2.0

The solenoid is 5.0 m long. What is the number of turns for the coils of the solenoid? 2.0 × 10^3 9)An electron is traveling horizontally from N to S in a region of space where the Earth's magnetic field is directed horizontally toward the north. What is the direction of the magnetic force on the electron? The magnetic force on the electron is zero. 10)What is the magnitude of the force on an electron moving with a velocity v = 5.43 × 106 m/s at an angle ? = 53.4° with respect to a magnetic field B = 7.72 × 10-2 T? 4.30 × 10^-15 N
