Given and are Hermitian what can you say about NA (1) ΩΛ+ ΑΩ (2) [2, A] (3) i[N, A) ?? and (4)

A spherical shell of radius R centered about the origin carrying a uniform surface charge o spins at an angular velocity o = (ê sin y +î cos y) w. To evaluate the vector potential A(0,0, z) (coordinates in Cartesian coordinates) in Coulomb gauge, we %3D can evaluate 27 Ã(0,0,2) = / « dcos 0' o' dợ'R*Ÿ (e', o') (1) where one recognizes dcos 0'do'R² as an area element on the spherical shell. What is Ý before doing any of the integration? [Express your answer in terms of {@,e', ø', y,R, z,£, §, ¿}].

The essence of the statement of the uniqueness theorem is that if we know the conditions the limit that needs to be met by the potential of the system, then we find the solution of the system , then that solution is the only solution that exists and is not other solutions may be found. If we know potential solutions of a system, can we determine the type of system that generate this potential? If so, prove the statement! If no, give an example of a case that breaks the statement!

I have put 1.37, 1.49, 1.50, 1.3, 1.3 x 10^-3 All have been wrong, I need help with (a).

Show that the commutator [ô, ô] - 28. 2i XI
