1. The problem statement, all variables and given/known data A diatomic molecule can be modeled as two point masses, m1 and m2, slightly separated. If the molecule is oriented along the y-axis, it has kinetic energy K when it spins about the x-axis. What will its kinetic energy (in terms of K) be if it spins at the same angular speed about (a) the z-axis (b) the y-axis? 2. Relevant equations K = 0.5Iω2 3. The attempt at a solution (a) I stays the same as the atoms are the same perpendicular distance from the origin. So the kinetic energy = K. (b) I = 0 as the perpendicular distance between each atom and the rotation axis (the y-axis) is 0. So, kinetic energy = 0. It would help me if you comment on my solution.
