Please write clearly the formulas and concepts behind it.
2. Two trains each moving with a constant velocity approach each other along a straight line. At a certain moment a man on the platform finds that the distance between the two trains is L and the two trains are going to collide with each other in a time 5L/7c. On the other hand another observer on one of the train sees the other train approaching him with a velocity 35cl37....

1. A speed selector is a device that uses both electric and magnetic fields to select particles with only a certain value of velocity. (a) If a positively charged particle goes through a region of space where the electric field points directly upwards and the magnetic field points out of the page, draw a free body diagram indicating the electric and magnetic forces this particle feels. (b) If the particle can go through this region without being deflected (that is,...
