  • question_answer
    The electric field due to a dipole at a distance\[r\] on its axis is [MP PMT 1993; RPET 2001;                                         MP PET/PMT 2002; BCECE 2003]

    A)                    Directly proportional to \[{{r}^{3}}\]

    B)                    Inversely proportional to \[{{r}^{3}}\]

    C)                    Directly proportional to \[{{r}^{2}}\]

    D)                    Inversely proportional to \[{{r}^{2}}\]

    Correct Answer: B

    Solution :

               \[E=\frac{1}{4\pi {{\varepsilon }_{0}}}.\frac{2p}{{{r}^{3}}}\]
