Q1. The diagram below shows a velocity selector. protons travelling between the 2 charged plates experience a force due to the electric field (E). A magnetic field B causes a force on the protons in the opposite direction. The protons are moving in a straight line between the 2 plates. +VD Figure 1 (a) What direction is the force on the electrons due to the charged plates (1 mark) tris 300 V. and they are 10
