Question 91 of 121

The time period of a simple pendulum is given by $T=2\pi \sqrt{\dfrac{l}{g}}.$ The measured value of the length of the pendulum is $10cm$ known to a $1mm$ accuracy. The time for $200$ oscillations of the pendulum is found to be $100$ second using a clock of $1s$ resolution. The percentage accuracy in the determination of $g$ using this pendulum is $x.$ The value of $x$ to the nearest integer is:-
