    Figure shows three points A, B and C in a region of uniform electric field \[\mathbf{\vec{E}}\mathbf{.}\] The line AB is perpendicular and BC is parallel lo the Field lines. Then which of the following holds good?

    A)  \[{{V}_{A}}={{V}_{B}}={{V}_{C}}\]                          

    B)         \[{{V}_{A}}={{V}_{B}}>{{V}_{C}}\]                          

    C)         \[{{V}_{A}}={{V}_{B}}<{{V}_{C}}\]                          

    D)         \[{{V}_{A}}>{{V}_{B}}={{V}_{C}}\] where \[{{V}_{A}}>{{V}_{B}}\] Vg and \[{{V}_{C}}\] represent the electric potential at points A. B and C respectively.

    Correct Answer: B

    Solution :

    Electric lines of force flow from higher potential to lower potential so,                 \[{{V}_{A}}={{V}_{B}}>{{V}_{C}}\]
