    A positively charged particle enters a magnetic field of value \[B\,\hat{i}\] with a velocity\[v\,\hat{j}\]. The particle will move along

    A)  z-axis              

    B)  - z-axis

    C)  - x-axis                        

    D)  - y-axis

    Correct Answer: B

    Solution :

    Force on the charged particle in magnetic field is \[F=q(v\hat{j}\,\,\times \,\,B\hat{i})\,\,=\,\,qvB(-\hat{k})\]which is - z-axis
