Question

Observation : (Length of the string = 100 cm]
No. Time taken to complete 20 oscillations
​

Answer 1

Answer:

Note the total time taken for twenty oscillations from the position of both the hands of the watch. As we need two observations for the same length, repeat steps 12 to 15 one more time. Repeat the experiment for lengths 60cm, 70cm, 80cm, 90 cm, 100cm, 110 cm, 120cm and 130cm.
