The period of oscillation of a simple pendulum in the experiment is recorded as 2.63 s, 2.56 s, 2.42 s, 2.71 s and 2.80 s respectively. The average absolute error is
Text Solution
Verified by ExpertsB
Average value \(\frac{2.63 + 2.56 + 2.42 + 2.71 + 2.80}{5}\)
2.62 sec
Now \(|\lambda T_1| \quad 2.63 - 2.62 \quad 0.01\)
\(|\lambda_{T_2}| \quad 2.62 - 2.56 \quad 0.06\)
\(\left| \lambda_{T_3} \right| \quad 2.62 - 2.42 \quad 0.20\)
\(|\lambda_{T_c}| \quad 2.71 - 2.62 \quad 0.09\)
\(|\lambda_{T_s}| \quad 2.80 - 2.62 \quad 0.18\)
Mean absolute error
\(\Delta T = \frac{|V_1| + |V_2| + |V_3| + |V_4| + |V_5|}{5}\)
\(-\frac{0.54}{5} - 0.108 - 0.11xc\)
