To determine the acceleration due to gravity using a simple pendulum.Apparatus: Pendulum, meter scale, stand, stop watch, vernier callipers.Procedure:1. The diameter of the bob is determined by using vernier callipers and then its radius (r) is calculated.2. Find the length of the pendulum l using a metre scale.3. Draw the bob aside giving a small amplitude and release it4. Then the pendulum starts its oscillation5. Find the time taken for ‘n' complete oscillation using stop watch and divide the time by ‘n' to get the time taken for one oscillation6. Calculate the value of l/T2.7. This experiment is repeated for different values of ‘l' (Say 30, 40, 50, 60, 70 and 80 cm) and find in each case the time period. The results are tabulated each time. and the average value of l/T28. Then the value of ‘g' can be calculated by the formula g = 4πr2( l/T2)
