Time periods of oscillation of the same simple pendulum measured using four different measuring clocks were recorded as \(4.62 \mathrm{~s}, 4.632 \mathrm{~s}, 4.6 \mathrm{~s}\) and \(4.64 \mathrm{~s}\). The arithmetic mean of these reading in correct significant figure is _______.
Pick an option to check your answer.
Answer & Solution
Correct Answer
(C) \(4.6 \mathrm{~s}\)
Step-by-step Solution
Detailed explanation
Sum of number by considering significant digit sum \(=4.6+4.6+4.6+4.6=18.4\)
\(\text { Arithmetic Mean }=\frac{\text { sum }}{4}=\frac{18.4}{4}=4.6\)
