The bob of a simple pendulum takes 8.0s to complete 10 oscillations. Determine the frequency of oscillation of the bob.
- A. 0.125Hz
- B. 1.25Hz
- C. 7.50Hz
- D. 8.00Hz
Correct Answer: B. 1.25Hz
Explanation
10 complete oscillations = 8.0s
1 complete oscillation (period) = \(\frac{8}{10}\)s
Frequency = \(\frac{1}{period}\) = \(\frac{1}{0.8} = 1.25Hz\)
