The time period of a simple pendulum is given by \(T=2\pi\sqrt{\frac{l}{g}}\). The measured value of the length of pendulum is 10 cm known to a 1 mm accuracy. The time for 200 oscillations of the pendulum is found to be 100 second using a clock of 1 s resolution. The percentage accuracy in the determination of 'g" using this pendulum is 'x'. The value of 'x' to the nearest integer is,
