One spring is attached to the ceiling at one end and body 1 of mass m₁ at the other end. The other spring hangs below body 1 with body 2 of mass m₂ at the other end. Both bodies are subjected to the downward force of gravity and the elastic forces from the springs. Determine the frequency of oscillation of body 2 if body 1 is held in place at its equilibrium point.The normalised wavefunction for an electron in an infinite 1D potential well of length 80 pm can be written:ψ=(0.587 ψ2)+(0.277 i ψ7)+(g ψ6). As the individual wavefunctions are orthonormal, use your knowledge to work out |g|, and hence find the expectation value for the energy of the particle, in eV.
