Calculated the change in g value in your district of Tamil nadu. (Hint : Get the latitude of your district of Tamil nadu from the Google). What is the difference in g values at Chennair and Kanyakumari?

Explanation

Chennai
`g'_(C) = g - omega^(2) R cos^(2) lambda`
`= 9.8 - (3.4 xx 10^(-2))`
` = 9.7677 ms^(-2)`
`g'_(K) = 9.8 - (3.4 xx 10^(-2)) xx (cos 0.1396)^(2)`
`= 9.748 ms^(-2)`
Difference in g value `Delta g = 0.0331 ms^(-2)`
`omega^(2)R - (2 xx 3.14/86400)^(2) xx 6400 xx 10^(3)`
`lambda = 13' (or) 0.2268 rad`.
