A) Griffiths works out (E); 5.2) the general solution to motion of a particle in "crossed E and B fields" (E points in the zdirection, B in the x-direction) Work carefully through his solution, make sure you follow it. Then, use it to answer the following: i) Suppose the particle starts at the origin at t=0, with a given velocity V\" = 0) = 1905'. Use Grifths' formal results (Eq. 5.6) to find the "special initial speed, v0, whose subsequent motion is simple straight-line constant-speed motion. (Verify that this answer makes sense by using elementary PHYS 133-sty1e right-hand rule arguments and the Lorentz force law)
