**Question:**An electron traveling due north enters a region that contains a uniform magnetic field that points due east. In which direction will the electron be deflected?**Options:**1. South2. Up3. East4. West5. Down**Explanation:**The problem presented involves an electron moving through a magnetic field, a fundamental concept in electromagnetism. When a charged particle like an electron moves through a magnetic field, it experiences a force given by the Lorentz force law. The direction of the force can be determined using the right-hand rule.In this scenario:- The electron moves due north.- The magnetic field points due east.To determine the direction of the force on the electron:1. Point your thumb in the direction of the electron's velocity (north).2. Point your index finger in the direction of the magnetic field (east).3. Because an electron has a negative charge, the force direction will be opposite to the direction your middle finger points when using the right-hand rule.By using the right-hand rule and reversing the direction due to the negative charge, the force (and hence the deflection direction) would be acting downward.Thus, the correct answer is **Down**.
