Time periods of oscillation of the same simple pendulum measured using four different measuring clocks were recorded as 4.62 ~s, 4.632 ~s, 4.6 ~s and 4.64 ~s . The arithmetic mean of these readings in correct significant figure is :

Correct answer: (C) 4.6 ~s. Sum of number by considering significant digi sum =4.6+4.6+4.6+4.6=18.4 Arithmetic Mean =sum/4=18.4/4=4.6

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 readings in correct significant figure is :

Sum of number by considering significant digi $\text {sum }=4.6+4.6+4.6+4.6=18.4$ Arithmetic Mean $=\frac{\text { sum }}{4}=\frac{18.4}{4}=4.6$

Hence, the correct answer is option: 'C'.
