Question
The figure shows three 0.0181 kg particles that have
been glued to a rod of length L=6.33 cm and
negligible mass. The assembly can rotate around a
perpendicular axis through point O at the left end. If
we remove one particle (that is, 33% of the mass), by
what percentage does the rotational inertia of the
assembly around the rotation axis decrease when
that removed particle is (a) the innermost one and (b)
the outermost one?
