Potential and dipole moment

  1. Feb 29, 2012 #1
    Could anyone help me with the following problem???
    Ammonia molecule has a dipole moment of 1.47D. Calculate the potential generated by this molecule at a point on a dipole axis at a distance of 52.0 nm from the centre of the dipole. how large will the potential be if an ion of charge q=1e=1.6*10^-19 C is brought at this point? it would be really helpful if you provide any required useful explanation...thank you...waiitng eagerly for ur response...

    The electric potential at a distance 'r' on the axis of a short dipole is given by

    [itex] V = \frac{1}{4 \pi \epsilon} \frac{2 p}{r^2} [/itex] where p is the dipole moment which according to the problem is given to be 1.47 D.
