Answer:

Step-by-step explanation:

Number of oscillations in 100 s is 68.

time taken to complete one oscillation = 100 / 68 s = 1.47 s

Use the formula for the time period of an oscillating body


T = 2\pi \sqrt{(L)/(g)}


T^(2) = 4\pi^(2) (L)/(g)}

In this equation substitute the value of T amd L and then find the value of g.
