The correct options are
A Velocity of the particle when it comes out from the magnetic field is
→v=v cos 60∘ →J B Time for which the particle was in magnetic field is πm3qB
D magnitude the momentum of the particle when it exits is mV AB=π3r=πmu3qBTime t=θω=π32πT=T6=π3qBDistance=vt=(πm3qB)v=πmv3Bq ![](https://search-static.byjusweb.com/question-images/byjus/infinitestudent-images/ckeditor_assets/pictures/11138/content_untitled-5.png)
