A magnetic field is non-uniform along the z axis between z = 0 and z = L, with t

Question

A magnetic field is non-uniform along the z axis between z = 0 and z = L, with the components (–Br, 0, Bz) expressed in cylindrical coordinates (r, ?, z), and uniform everywhere else: B = Bz. An electron and a proton, initially in cyclotron motion around Bz at z = 0 with the centers of their orbits at r = 0, are moved to z = L/2 and then released. Which of the following describes correctly the subsequent motions of these particles:

Question 16 of 19 Map do sapling learning Bz A magnetic field is non-uniform along the z axis between z = 0 and z = L, with the components (-B, o, B) expressed in cylindrical coordinates (r, , z), and uniform everywhere else: B = Bz. An electron and a proton, initially in cyclotron motion around B, at z = 0 with the centers of their orbits at r= 0, are moved to z= L2 and then released Which of the following describes correctly the subsequent motions of these particles: O While gyrating around Bz, both particles move to z = L. O While gyrating around Bz, both particles move back to z- 0. Br The electron moves to z = 0 and the proton to z = L. O Particles now gyrate both around B, and B, at z= 2. Bz

Explanation / Answer

While gyrating around Bz, both particles move to z = L
