Solved: A diatomic molecule can be modeled as two point
Chapter 9, Problem 2DQ(choose chapter or problem)
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\(y \text {-axis }\), it has kinetic energy when it spins about the \(x \text {-axis }\). What will its kinetic energy (in terms of
) be if it spins at the same angular speed about
(a) the \(z \text {-axis }\) and
(b) the \(y \text {-axis }\)?

ANSWER:
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
