The time period of a simple pendulum is given by T = 2n L/g . The measured value of L is 20.0 cm using a scale of least count 1 mm and time t for 100 oscillations is found to be 90 s using a watch of least count 1 s. Find the value of g (in m s²) up to appro- priate significant figure, stating the uncertainity in the value of g.
