Answer
Given,
Period of the Pendulum, T= 1 s
acceleration due to gravity, g = 9.8 m/s²
Length of Bob = 0.2482 m
Loss of time in the clock = 1.5 minutes/ day
Loss of time in 1 oscillation
= 
= 0.001042
Hence, time period, T = 1 + 0.001042
T = 1.001042 s
a) Using Time period of oscillation formula



Free fall acceleration at the clock location = 9.77 m/s²
b) Length of pendulum bob to keep it perfect time



Hence, Length of pendulum bob is equal to 0.2475 m.
Bob is the fourth child, as the sentence states "Bobs FATHER"
