    Dipole moment of non-uniform surface charged sphere

    I'm trying to find the dipole moment of a non-uniform surface charge distribution on a sphere of radius a: The surface charge distribution is: \sigma = \sigma_{0} cos \theta where theta is the polar angle. Here is what I did: \vec{p} = \int\vec{r}\sigma dA = \int r \sigma_{0} cos...

    What is the Dipole Moment of Helium at STP?

    Hi there, I was wondering if you could help me with a question I have (I've posted it here as opposed to the homework help forums cos I alwso want a little bit of the theory explained ). The relative permittivity of helium at STP is 1.000047. Estimate the magnitude of the dipole moment...

    Can You Help Me Understand Molecular Dipole Moments?

    Molecular dipole moment? What is a Molecular Dipole moment. My book explains it but i still don't get it. And here is a problem that ask me about it. Which molecule in each pair has the greater dipole moment a. SO2 or SO3 b. ICl or IF c. SiF4 or SF4 d. H2O or H2S Give the reason for...

    Net charge VS dipole moment in E field by infinite line charge

    could anyone compare the behaviors of (1) an object with a net charge but no dipole moment and (2) an object with net charge but with a dipole moment when placed in the electric field produced by an INFINITE line charge? thankyou
