    The given figure shows the electric lines of force emerging from a charged body. If the electric field at A and B are EA and EB respectively and if the displacement between A and B is r, then

    A) \[{{E}_{A}}>{{E}_{B}}\]                                 

    B) \[{{E}_{A}}<{{E}_{B}}\]

    C) \[{{E}_{A}}=\frac{{{E}_{B}}}{r}\]                               

    D) \[{{E}_{A}}=\frac{{{E}_{B}}}{{{r}^{2}}}\]

    Correct Answer: A

    Solution :

    At point A the electric lines are more dense than  at B, so \[{{E}_{A}}>{{E}_{B}}.\]
