Acharged particle of mass m and positive charge q moves in uniform electric and magnetic fields, e~ and b~ , both pointing in the z direction. the net force on the particle is f~ = q(e~ + ~v × b~ ). at t = 0 sec, the particle’s position is (x0, y0, z0) with initial velocity ( ˙x0, y˙0, z˙0). (a) solve the equations and express the position and velocity of the particle as a function of time.

Calculate the minimum energy required to remove one proton from the nucleus 126c. this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c.) express your answer with the appropriate units. emin e m i n = nothing nothing request answer part b how does the proton-removal energy for 126c compare to the binding energy per nucleon for 126c, calculated using eb=(zmh+nmn−azm)c2?
