Problem
Two identical particles, each of mass m, are fixed at a distance a from a given axis. If both particles are moved radially outward to a new distance 2a, how does the moment of inertia about the same axis change?
(a) Becomes double (2I0)
(b) Remains the same (I0)
(c) Becomes quadruple (4I0)
(d) Becomes eight times (8I0)
