    A positively charged particle moving with velocity v enters a region of space having a uniform magnetic field B. The particle will experience the large deflecting force, when  the angle between v and B is:

    A) \[{{0}^{o}}\]             

    B) \[{{45}^{o}}\]

    C)  \[{{90}^{o}}\]            

    D) \[{{180}^{o}}\]

    Correct Answer: C

    Solution :

     Key Idea: Maximum force is experienced when angle between v and B is \[{{90}^{o}}.\] Force experienced by a particle of change q, travelling with velocity \[v\] in magnetic field B is given by \[F=qvB\,\sin \theta \] where \[\theta \] is angle between \[v\] and B \[\therefore \] \[{{F}_{m}}=qvB\sin {{90}^{o}}=qvB\]
