9. [-/4 Points] DETAILS SERPSE10 40.2.P.009. For a quantum particle of mass m in the ground state of a square well with length L and infinitely high walls, the uncertainty in position is Ax * L. (a) Use the uncertainty principle to estimate the uncertainty in its momentum. (Use the following as necessary: ħ, m, and L.) Ap≈ (b) Because the particle stays inside the box, its average momentum must be zero. Its average squared momentum is then (p²) ~ (Ap)². Estimate the energy of the particle. (Use the following as necessary: ħ, m, and L.) E = (c) State how the result of part (b) compares with the actual ground-state energy. This answer has not been graded yet. Read It Need Help?
