Starting from rest, a proton has been accelerated in the +x-direction through a potential difference of 5.00 mv. then it enters a uniform magnetic field of magnitude 0.03 t , which is directed in the positive z-direction. this field is present only in the region 0 ≤ x ≤ 1.00 m. calculate the y-component of the proton’s momentum as it leaves the magnetic field.
