You have two pendulums. Pendulum A is a uniform rod of mass m and length d, attached by a frictionless hinge to the ceiling. Pendulum B is a small ball of the same mass m whose center of mass is the same distance d from where the fishing line holding it attaches to the ceiling (it can be well approximated as a simple pendulum). Determine and simplify the ratio of the period of in terms of the given variables and g. TA/TB pendulum A to the period of pendulum B
