Question 1
What is the formula for the Lorentz force?
- F = qE
- F = q(v × B)
- F = q(E + v × B)
💡 Hint: Remember to include both fields in your formula.
Question 2
True or False: A charged particle moving in a magnetic field experiences a force parallel to its velocity.
- True
- False
💡 Hint: Consider the direction of the force compared to motion.

Challenge Problems
Push your limits with challenges.
Question 1
A proton enters a region with an electric field of 500 N/C and a magnetic field of 0.1 T. Calculate the total force acting on the proton if it is moving at a velocity of 2×10^5 m/s at an angle of 30 degrees to the magnetic field.
💡 Hint: Don't forget to use trigonometry for the angle with the magnetic field.
Question 2
An electron (mass = 9.11×10^-31 kg) is accelerated through a potential difference of 60 V. Calculate its final velocity and the radius of its path when it enters a magnetic field of 0.2 T.
💡 Hint: Make sure to calculate charge energy conversion correctly.
