The time period of a simple pendulum is given by T=2π√1/g. The measured value of the length of pendulum is 10cm known to a 1mm accuracy. The time for 200 oscillations of the pendulum is found to be 100 s 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
