3. A simple pendulum takes 32 s to complete 20 oscillations. What is the time period of the pendulum?

Answers (1)

Given that,
A simple pendulum takes 32 s to complete 20 oscillations. It means,
No. of oscillation = 20, and 
Total time is taken = 32 s
According to question,
Time period = (T) 
                      T=\frac{total\ time\ taken}{No.\ of\ oscillation}
                     T=\frac{32}{20} = 1.6 s
