STANDARD Physics Simple Pendulum MCQ Question
Type: MCQ-numerical-Medium-Class 11
In an experiment, the period of oscillation of a simple pendulum was observed to be 2.63 s, 2.56 s, 2.42 s, 2.71 s and 2.80 s. The mean absolute error is
A
0.11 s
B
0.12 s
C
0.13 s
D
0.14 s
Correct Answer
Option A
Detailed Explanation
The mean period of oscillation is calculated as T_mean = (2.63 + 2.56 + 2.42 + 2.71 + 2.80) / 5 = 2.62 s. The absolute errors are calculated for each measurement, and the mean absolute error is ΔT_mean = (0.01 + 0.06 + 0.20 + 0.09 + 0.18) / 5 = 0.11 s.
