... Charge of 10–6 C is given to a 2-m2 thin plate. Afterwards, an electron with the mass 9.109×10–31 kg with the charge 1.602×10–19 C is held in a distance 10 cm from the plate. (a) Determine the force acting on the electron. (b) If the electron is released, determine the speed of the electron when it ...

History of electromagnetic theory
For a chronological guide to this subject, see Timeline of electromagnetic theory.The history of electromagnetic theory begins with ancient measures to deal with atmospheric electricity, in particular lightning. People then had little understanding of electricity, and were unable to scientifically explain the phenomena. In the 19th century there was a unification of the history of electric theory with the history of magnetic theory. It became clear that electricity should be treated jointly with magnetism, because wherever electricity is in motion, magnetism is also present. Magnetism was not fully explained until the idea of magnetic induction was developed. Electricity was not fully explained until the idea of electric charge was developed.
