The Attempt at a Solution

tried looking it up, couldn't find anything. what does it mean when it talks about the 'electron's state'? is that some wavefuction?
i don't know whether i'd be able to do que b or not, since i don't know how to do part a

Thank you for your post. I am a scientist and I would be happy to help you with your question.

First, let me clarify what is meant by the "electron's state." In quantum mechanics, the state of a particle is described by a wavefunction, which is a mathematical function that contains all the information about the particle's position, momentum, and other observable quantities. In the case of an electron in a hydrogen atom, the wavefunction is a function of the electron's position in space, and it is described by the quantum numbers n, l, and m. These quantum numbers represent the energy, angular momentum, and magnetic moment of the electron, respectively.

Now, to address part a of your question, we need to consider the effect of a magnetic field on the electron's state. When a magnetic field is applied, the Hamiltonian (the operator that describes the energy of the system) changes to include an additional term that takes into account the interaction between the electron's magnetic moment and the magnetic field. This term is given by:

H' = e/(2*mass of electron)*Lz*Bz

Where e is the charge of the electron, m is its mass, Lz is the z-component of the angular momentum operator, and Bz is the strength of the magnetic field in the z-direction. Since the electron's state is described by a wavefunction, we can use the time-independent Schrodinger equation to find out how the state changes in the presence of this additional term. The time-independent Schrodinger equation is given by:

H*ψ = E*ψ

Where H is the Hamiltonian, ψ is the wavefunction, and E is the energy of the system. Since the electron's state is already a solution of the time-independent Schrodinger equation in the absence of a magnetic field (i.e. H*ψ = E0*ψ), we can substitute this into the equation above to get:

(H + H')*ψ = (E0 + H')*ψ

This shows that the electron's state remains a solution of the time-independent Schrodinger equation even when a magnetic field is applied, but the energy of the system is now given by E0 + H'. This means that the energy of the electron's state increases due to the presence of the magnetic field.

Moving on to part b of your question, we can use the same approach to
