Estimate the maximum rotational energy (in electron-volts) for a free and freely-spinning diatomic hydrogen molecule in the L = 2 quantum state.
 
  The equilibrium separation for the atoms in the H2 molecule is 0.075 nm. (1 eV = 1.60  10-19 J, mproton = 1.67  10-27 kg, h = 6.626  10-34 J  s)
  A) 0.044 eV B) 0.011 eV C) 0.022 eV D) 0.033 eV

Question 2

At a point 10 m away from a long straight thin wire, the magnetic field due to the wire is 0.10 mT. What current flows through the wire? (0 = 4  10-7 T  m/
