If a pendulum has a period of exactly 1.00 sec. at the equator, what would be its period at the south pole? Assume the earth to be spherical and rotational effect of the Earth is to be taken.
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
T = 1– 
= 0.998 s
Sol. Period of pendulum = 
Let T 1 be the time period at pole and T 2 is time period at equator.
= 
T 1 = 1 – 
. Since 
<< 1
So , T 1 = 1 – 
= 1 – 
× 
= 0.998 second Ans.
