1. A 0.32-mC particle moves with a speed of 16 m/s through a region where the magnetic field has strength of 0.95 T. At what angle to the field is the particle moving if the force exerted on it is
a) 4.8 x 10-6 N
b) 3.0 x 10-6 N
c) 1.0 x 10-7 N
Solution:
q = 0.32μC v = 16m/s B = 0.95T θ = ?
2. An electron moving with a speed of 9.1 x 105 m/s in the positive x direction experiences a zero magnetic force. When it moves in the positive y direction, it experiences a force of 2.0 x 10-13 N that points in the negative z direction. What is the direction and magnitude of the magnetic field?
Solution:
3. A particle with a charge of 14 mC experiences a force of 2.2 x 10-4 N when it moves at right angles to a magnetic field with a speed of 27 m/s. What force does this particle experience when it moves at the speed of 6.3 m/s at an angle of 250 relative to the magnetic field?
Solution:
4. An electron moving in the positive x direction, at right angles to a magnetic field, experiences a magnetic force in the positive y direction. What is the direction of the magnetic field?
Solution:
