1.

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»

Solution :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))`.
