Problem

A simple pendulum of length

0.25\,\text{m}

performs small oscillations. It is driven by an external periodic force. Calculate the driving frequency (in Hz) that will produce resonance. Take

g = 9.8\,\text{m\,s}^{-2}

. (a)

0.50\,\text{Hz}

(b)

1.00\,\text{Hz}

(c)

2.00\,\text{Hz}

(d)

6.30\,\text{Hz}
