LORENTZ FORCE SAMPLE PROBLEM SET # 1 1

SAMPLE PROBLEMS: LORENTZ FORCE

GENERAL DIRECTIONS:

?Refer to the formulas discussed in the lecture handouts in ManageBac.

?Draw the vector diagrams for each situation.

?Solve for what is being asked; use appropriate units.

1.A 4.5nC charge moves at 6.8 km/s, at a

direction of 45 degrees across a magnetic field directed downward. The magnetic field has a magnitude of 85μT. What is the magnitude and direction of the Lorentz Force?

2.A25μC charge is moving at 2 km/s. This

particle is moving into a 0.5T field, directed downwards, at a 35-degree angle. What is the magnitude and direction of the Lorentz Force?

3.A 95 μT magnetic field emitted by a magnet is

projected 180-degrees from the horizontal.

A particle with a charge of 2.76 x 10-4C is

traveling at 4.2 km/s against this magnetic field with a bearing of 35 degrees from the horizontal. What is the magnitude and direction of the Lorentz Force?
