Charged Particles in Electric and Magnetic Fields

These questions cover the field skills that school trial papers test again and again: field strength between plates, work and energy, parabolic paths across plates, the magnetic force and its direction, circles in a magnetic field, velocity selectors and identifying particles. Use $q_e=1.602\times 10^{-19}$ C, $m_e=9.109\times 10^{-31}$ kg, $m_p=1.673\times 10^{-27}$ kg and $1\text{ u}=1.661\times 10^{-27}$ kg. They start easy and get harder. Stuck?
