Neco 2022 Physics Question 10 diagram

In the laboratory setup shown, a simple pendulum of length \(0.80\ \text{m}\) is suspended from a fixed support. The bob is displaced a small angle and released. A stopwatch is used to time the oscillations. The recorded time for \(20\) complete oscillations is \(28.0\ \text{s}\). The stopwatch gains \(0.05\ \text{s}\) per timing.\n\n(i) Calculate the theoretical period of the pendulum using \(g=9.8\ \text{m s}^{-2}\).\n\n(ii) Determine the corrected period of the pendulum based on the recorded time.

Answer Options

A. Theoretical period = 1.70 s; Corrected period = 1.50 s
B. Theoretical period = 1.85 s; Corrected period = 1.35 s
Correct Answer C. Theoretical period = 1.79 s; Corrected period = 1.40 s
D. Theoretical period = 1.60 s; Corrected period = 1.45 s
Correct Answer
C
Correct Option:
Theoretical period = 1.79 s; Corrected period = 1.40 s
