4 cards from this section. Quick, good the night before a test.
What is the formula for the force experienced by a charged particle in an electric field?
Think about how charge and electric field strength relate.
In which direction does a positive charge move in an electric field?
Consider the nature of positive charges.
What is the force experienced by a charged particle in an electric field?
Remember the relationship between force, charge, and electric field.
True or False: A charged particle will always move in a straight line in a magnetic field.
Think about the influence of forces in curved paths.
A negatively charged particle with a mass of 9.11 x 10^-31 kg and a charge of -1.6 x 10^-19 C moves with a velocity of 2.0 x 10^6 m/s in a magnetic field of 0.3 T. What is the radius of its path?
Pay attention to using the absolute value of charge for the calculation!
If a particle enters a region of uniform electric and magnetic fields that are perpendicular to each other and maintains a steady path, what must be true about its motion? Describe the conditions.
Consider Newton's second law and how forces interact.
