If a pendulum has a period of exactly 1....

If a pendulum has a period of exactly `1.00sec` 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 Experts

The correct Answer is:
`T = 1 - (1)/(2) (4pi^(2))/((86400)^(2)) xx (10^(3))/(9.8) = 0.998s` .
