Let's apply the uncertainty principle to an electron that is confined inside a cubical box 1.0 × 10-10 on a side. (a) Estimate the minimum uncertainty in the x component of the electron's momentum. (b) If the electron has momentum with magnitude equal to the uncertainty found in part (a), what is its kinetic energy? Express the result in joules and in electronvolts.
