The charged particle in the figure is a proton and the uniform magnetic field B is directed along the x-axis. Only the magnetic force acts on the proton. The proton starts its motion at x = 0 plane and reaches x = k plane after t amount of time. Which of the following are true for the proton's motion?

proton. The proton starts its motion at x = 0 plane and reaches x = k plane
after t amount of time. Which of the following are true for the proton's
motion?
I. t increases with decreasing v(YZ)
II. t increases with decreasing v(x)
I. The path length to reach x = k plane (grey line)
increases with increasing B field magnitude.
IV. The path length to reach x = k plane (grey line)
increases with decreasing v(x).
