Explanation / Answer

Here ,

let the acceleration due to gravity at the location is g

length , L = 2.6 m

time period of pendulum = time taken for 1 oscillation

T = 2 * (25.6)/(8)

T =6.4 s

Now , T = 2 pi * sqrt(L/g)

6.4 = 6.282 * sqrt(2.6/g)

solving for g

g = 2.51 m/s^2

the acceleration due to gravtiy at the location is 2.51 m/s^2
