In a region of space, a uniform magnetic field B exists in the x-direction. An electron is fired from the origin with its initial velocity u making an angle `alpha` with the y direction in the y-z plane. In the subsequent motion of the electron,

In a region of space, a uniform magnetic field B exists in the y direction. A proton is fired from the origin, with its initial velocity v making a small angle alpha with the y direction in the yz plane. In the subsequent motion of the proton,
