In five successive measurment, the time period is found to be `0.52s, 0.56s,0.57s,0.54s and 0.59s`. the least count of the watch used for the measurement of time period is `0.01s`. Which of the following satement `(s)` is `(are)` true?A. The error in the measurement of `r` is `10%`B. The error in the measurement of `T` is `3.57%`C. The error in the measurement of `T` is `2%`D. The error in the determined value of `g` is `11%`
