State the type of field, or fields, that may produce a force on a particle that is uncharged and moving.
State the type of field, or fields, that may produce a force on a particle that is charged and stationary.
State the type of field, or fields, that may produce a force on a particle that is charged and moving at right-angles to the field.
Particle X has mass $3.32 \times 10^{-26}\,\text{kg}$ and charge $+1.60 \times 10^{-19}\,\text{C}$. The particle is moving in a vacuum at speed $7.60 \times 10^{4}\,\text{m s}^{-1}$. It enters a region of uniform magnetic field that is normal to the direction of travel of the particle. The particle travels in a semicircle of diameter $12.2\,\text{cm}$, as shown in Fig. 6.1.
State which way the uniform magnetic field points.
Calculate the magnetic flux density.
A second particle Y has a mass smaller than that of particle X in (b) and the same charge. It enters the region of uniform magnetic field in (b) with the same speed and along the same initial path as particle X. On Fig. 6.1, draw the path of particle Y in the magnetic field region.
