3 cards from this section. Quick, good the night before a test.
What is the formula for the force on a charged particle in an electric field?
Think about how charge relates to force and field strength.
In which direction does a negative charge move in an electric field?
Remember the relationship between charge types and field direction.
What is the equation for force acting on a charged particle in an electric field?
Remember the definitions of electric force.
True or False: A charged particle in a magnetic field can only move in a straight line.
Think about circular motion and centripetal forces.
A particle with charge +3 × 10^-19 C and mass 2 × 10^-27 kg is accelerated in an electric field of strength 5 N/C. Calculate the acceleration of the particle.
Apply Newton's second law clearly to find acceleration.
Two charged particles enter a uniform electric field and then a magnetic field at 90 degrees, calculate their paths given their initial velocities and charges.
Break down the motion into components to simplify calculation.
