16.4 Exercise 1

An engineer builds two simple pendula. Both are suspended from small wires secured to the ceiling of a room. Each pendulum hovers 2 cm above the floor. Pendulum 1 has a bob with a mass of $\text{10} \text{kg}$. Pendulum 2 has a bob with a mass of $\text{100 kg}$. Describe how the motion of the pendula will differ if the bobs are both displaced by $\text{12}º$.
