Answer:
Explanation:
Expression for time period of pendulum is given as follows
[tex]T=2\pi\sqrt{\frac{l}{g} }[/tex]
where l is length of pendulum and g is acceleration due to gravity .
Putting the given values for first place
[tex]2.67=2\pi\sqrt{\frac{l}{9.77} }[/tex]
Putting the values for second place
[tex]T=2\pi\sqrt{\frac{l}{9.81} }[/tex]
Dividing these two equation
[tex]\frac{T}{2.67} =\sqrt{\frac{9.77}{9.81} }[/tex]
T = 2.66455 s.
