Question
Conceptual question: Three charged particles share identical electric charges and masses. They are entering a constant uniform magnetic field B and following the circular paths with radii shown in pictures (Fig. 1). This field is directed towards the page. Discuss and analyze the following questions. 1. Determine the sign of electric charge that particles have. Explain. 3 pts 2. Find direction of magnetic forces acting on these particles. Explain. 3 pts 3. All three particles are participating in uniform circular motion. Give your reasoning.
Explanation / Answer
(a) The nature of charge is positive. And the constant force F= qvB acts on the charged particle. According to Fleming
