    Electric field strength due to a diple at a point on the axial line of dipole is

    A)  from positive charge to negative charge

    B)  from negative charge to positive charge

    C)  along the equatorial line

    D)  at an angle to axial line

    Correct Answer: B

    Solution :

     \[E=\frac{1}{4\pi {{\varepsilon }_{0}}}.\frac{2P}{{{r}^{3}}}\] The direction of electric field E is along the axis of the dipole from negative charge towards positive charge.
