Question

The picture shows the paths of some neutral and charged particles in a bubble chamber, which contains an undisturbed liquid heated above its boiling point. The idea is that bubbles begin forming on nucleation centers such as surface irregularities, or particles moving through the liquid. These bubbles allow you to see the trails of the particles. Particles enter the chamber from the left. A uniform magnetic field is directed out of the screen toward you. A certain incoming particle (whose trail is not visible) splits into 3 other particles, including those that follow paths A and B. What is the sign of the charge of the particle that follows path A? What is the sign of the charge of the particle that follows path B? Explain your answers.

Explanation / Answer

Charge a negative

Charge b positive

using right hand rule force on a positive charge should be downward and rotation should be clockwise
