Angular SHM of a dipole in electric field

  1. Mar 28, 2010 #1
    I was reading some topics related to electrostatics where i came accross ANGULAR SHM OF A DIPOLE. I could understand everything in SHM. but i cant relate it with electric field. i've some doubts based on the conventions used here... can any1 help me...... and this is it... it's given that (restoring couple)c=I.r''; r=angular displacement... double differential
    Also in general, w(angular velocity)=sqrt(k/m) and i'm familiar with this. but how did this come....? w=sqrt(pE/I); p=dipole moment, E electric field
