A diatomic molecule can be modeled as two point masses, ?m?1 and ?m?2, slightly separated (?Fig. Q9.2?). 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 and (b) the y-axis?

Solution 2DQ Step 1 of 2: Given that, the kinetic energy of the diatomic molecule when it is rotating along x-axis is K. Since the diatomic molecules are at equal distance from the axis of rotation along x-axis and y-axis, as shown in the figure below
