Question
Write the following steps in sequence to determine the time period of a simple pendulum.
(A) Start the stopwatch when the bob is at the mean or extreme position and find the time taken by the pendulum to complete 20 oscillations.
(B) Take a simple pendulum of length (l) and a stopwatch.
(C) Move the bob of the pendulum to one side and release it.
(D) Divide the time taken for 20 oscillations by 20 and obtain the time period (T) of the simple pendulum.

Solution
The correct option is A BCAD
- Take a simple pendulum of length (l) and a stopwatch (B).
- Move the bob of the pendulum to one side and release it (C).
- Start the stopwatch when the bob is at the mean or extreme position and find the time taken by the pendulum to complete 20 oscillations (A).
- Divide the time taken for 20 oscillations by 20 and obtain the time period (T) of the simple pendulum (D).
Hence, option A is correct.
