Consider an atom with one electron. The intrinsic spin of the electron isho (The o is ho the Pauli spin operator) and magnetic moment is , e The atom is placed in an 2mc external magnetic field B in the direction. The value of (,) is, (a) tanh(BugB) (b) sinh(Bu,B) (c) (d) e 2 +e-Aug 2e-Aug +e -Bugh The instantaneous electric and magnetic fields created by a point source at the origin at a distances are given by Dcos at and H-Ecos a where , D, E are constant 2.mer Hor and the units vectors are 7, 6, and 6. Calculate the averaged power radiated by the source (a) c'DE (b) cA (c) c'DE (d) AB
