A student uses a simple pendulum of exactly \( 1 \mathrm{~m} \) length to determine \( g \), the acceleration due to
\( \mathrm{P} \) gravity. He uses a stopwatch with the least count
W of 1 second for this and records 40 seconds for 20 oscillations. For this observation, which of the following statements is true?
(a) Error \( \Delta T \) in measuring \( T \), the time period, is \( 0.05 \) seconds.
(b) Error \( \Delta T \) in measuring \( T \), the time period, is 1 second.
(c) Percentage error in the determination of \( g \) is \( 5 \% \).
(d) Both (a) and (c)
