Question

An electric dipole whose modulus is constant and whose moment is equal to `p` rotates with constant angular velocity `omega` about the axis draws at right angles to the axis of the dipole and passing through its midpoint. Find the power radiated by such a dipole.

Answer 1

The rotating dispole has moments
`p_(x) = pcos omegat, p_(y) = p sin omegat`
Thus `P = (1)/(4pi epsilon_(0))(2)/(3c^(3))omega^(4)p^(2) (p^(2)omega^(4))/(6pi epsilon_(0)c^(3))`.
