Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
