# Question

The forces acting on a simple pendulum are shown in Fig. 13.26.

(a) Show that, for the small angle approximation (sin θ ≈ θ), the force producing the motion has the same form as Hooke’s law.

(b) Show by analogy with a mass on a spring that the period of a simple pendulum is given by T = 2π√L/g.
