    The ratio of electric fields on the axis and at equator of an electric dipole will be                                [RPMT 2002]

    A)                    1 : 1

    B)                                      2 : 1

    D)                                      None of these

    Correct Answer: B

    Solution :

               \[{{E}_{a}}=k\frac{2p}{{{r}^{3}}}\] and \[{{E}_{E}}=\frac{kp}{{{r}^{3}}}\]Þ \[\frac{{{E}_{a}}}{{{E}_{E}}}=\frac{2}{1}\]
