A proton and an electron are moving at a particular instant as shown in the attachment. (a) On a similar diagram, show the direction of the electric field and magnetic field that the proton produces at the location of the electron. (b) Show the direction of the electric force and the magnetic force that the proton exerts on the electron. (c) Similarly, show the direction of the electric field and the magnetic field that the electron produces at the location of the proton. (d) Show the direction of the electric force and the magnetic force that the electron exerts on the proton. (e) Consider carefully your results from (b) and (d). Are the magnetic forces on electron and proton in opposite directions? Does reciprocity hold for magnetic forces? (f) Will the total momentum of the two particles remain constant? Is this a violation of conservation of momentum for an isolated system?
