    Which one of the following will experience maximum magnetic force while projected with same perpendicular velocity and in same magnetic field strength region?

    A)  Electron                             

    B)  Proton  

    C)  \[H{{e}^{+}}\]                                  

    D)  \[Li{{\,}^{++}}\]

    Correct Answer: D

    Solution :

                    Force, \[F=qvB\sin \theta \]     \[=qvB\](when\[\sin \theta =\sin 90{}^\circ =1\]) \[\Rightarrow \]               \[F\propto q\](i.e., charge) As \[L{{i}^{++}}\]has maximum charge among four particles. So, it will experience maximum force.
