A proton and a deuteron, each moving with velocity vecv, enter simultaneously in the region of magnetic field vecB acting normal to the direction of velocity. Trace their trajectories establishing the relationship between the two . |

Answer» Solution :We know that when a particle of mass .m. and charge .Q. moving with a VELOCITY `vecv` enters a region of MAGNETIC field `vecB` acting NORMAL to the direction of velocity, it describes a circular path of radius `r = (mv)/(qB)`. As per question `v_("proton") = v_("deuteron")` and charges are also same. But `m_("deuteron") = 2m_("proton") `. As a result, `r_("deuteron") = 2r_("proton")` The trajectories have been traced in fig.
