The time period of a simple pendulum is given by T = 2π (l)/(g) ....

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:-
