A source of ions at point O produces a slightly diverging beam with half-angle of divergence α0≪1. In order to collimate (re-focus) the beam, one can apply a uniform magnetic field along the z-axis (see the figure below). If all the ions have the same initial velocity and specific charge qm, the beam focuses at point A, again at point B and so on. Assuming that qm=10^5C/kg , B=10^−3T and v=100m/s find the distance
OA¯¯¯¯¯ in meters
1.5 meters

answer \?????????
1.2
pretty sure it is 5.6 meters
5.6 is wrong
is 1.2 correct
@tttt Mind your language. His answer might have been wrong but he has been trying to help you nonetheless. :)
solution?
please don't copy all answers for them....
Please.. Avoid cheating a wrong answer.
Post a correct answer.. You fool!
