Challenge Problems
Push your limits with challenges.
Question 1
A particle with mass 1 kg and charge 4 C is moving at a speed of 6 m/s through an electric field of 10 N/C and a magnetic field of 0.2 T. What is the total Lorentz force acting on it?
💡 Hint: Calculate both components of the forces separately before adding them.
Question 2
Explain why the Lorentz force can cause a charged particle to move in a circular path. Discuss in the context of charge mass ratios.
💡 Hint: Consider how centripetal acceleration relates to force and motion.
