What is the expectation value for the kinetic energy of an electron in a box if $ \Psi =\left( \frac { 2 }{ L } \right) \sin\left( \frac { 2\pi x }{ L } \right) $ over the entire region from $0$ to $L$?

Note:

  • $L = 1.00 \text{ nm}$
  • $h = 6.62608\times { 10 }^{ -34 } \text{J s}$
  • ${ m }_{ e }=9.10938\times { 10 }^{ -31 } \text{ kg}$
