A pendulum clock giving correct time at a place where g=9.800 m s−2 is taken to another place where it loses 24 seconds during 24 hours. Find the value of g at this new place.
For the pendulum,
T1T2=√(g2g1)
Give that, T2=2 sec, g1=9.8 m/s2
T1=24×3600(24×3600−24)2
=2×36003599
Now, g2g1=(T1T2)2
∴ g2=(9.8) (35993600)2
=0.795 m/s2
