Minimizing Rotational Inertia
A system consists of two point masses, each of mass m, connected by a massless rod of length 2L. The system rotates about an axis that is perpendicular to the rod and located a distance x from the rod’s center. For which of the following values of x is the rotational inertia of the system minimized?
A
x = L
B
x = L/2
C
x = L/√2
D
x = 0
