2. To "observe" small objects, one measures the diffraction of particles whose de Broglie wavelength is approximately equal to the object's size. Find the kinetic energy (in electron volts) required for electrons to resolve (a) a large organic molecule of size 10.0 nm, (b) atomic features of size 0.100 nm, and (c) a nucleus of size 10.0 fm.
