We have potential of

V (x) = ( 0, 0 ≤ x ≤ a.
  ∞, elsewhere.

a) Find the ground state energy and the first and second excited states, if an electron is enclosed in this potential of size a = 0.100 nm.

b) Find the ground state energy and the first and second excited states, if a 1 g metal sphere is enclosed in this potential of size a = 10.0 cm.

c) Are the quantum effects important for both systems? Explain why or why not.

d) Use the uncertainty principle to estimate the velocities of the electron and the metal sphere.
