Question
A wall clock uses simple pendulum. It is accurate at earth surface .If it is taken to high altitude :
Options
A.it will run fast
B.its length should be increased to keep it accurate.
C.its length should be decreased to keep it accurate.
D.Even if length is changed it cannot be accurate.
Solution
T = 2π 
, At high altitude value of g decreases
∴ length of pendulum must be decreased to keep correct time.
, At high altitude value of g decreases ∴ length of pendulum must be decreased to keep correct time.
