    A conductor AB of length\[l\]moves in x - y plane with velocity \[\vec{v}={{v}_{0}}(\hat{i}-\hat{j})\]. A magnetic field \[\overset{\to }{\mathop{B}}\,={{B}_{0}}(\hat{i}+\hat{j})\] exists in the region. The iduced Emf is

    A) zero

    B) \[{{B}_{0}}l{{v}_{0}}\]

    C) \[{{B}_{0}}l{{v}_{0}}\]

    D) \[\sqrt{2}{{B}_{0}}1{{v}_{0}}\]

    Correct Answer: A

    Solution :

    [a] \[\vec{\ell },\,\vec{v}\], and \[\vec{B}\] are coplanar.
