Problem
The region between x=0 and x=L is filled with a uniform steady magnetic field −B0k. A particle of mass m, positive charge q, and velocity v0i travels along the x-axis and enters the magnetic-field region. Neglect gravity throughout the question.
(a) Find the value of L if the particle emerges from the magnetic-field region with its final velocity at an angle 30∘ to its initial velocity.
(b) Find the final velocity of the particle and the time spent by it in the magnetic field if the magnetic field now extends up to 2.1L.
