If earth stop spinning about its own axis, what will be the change in acceleration due to gravity on its equator ? The radius of earth is `6.4xx10^(6)` m and its ngular speed is `7.27xx10^(-5)rad//s`.

Text Solution

Verified by Experts

Effective acceleration due to gravity is given by

`g' = g-R omega^(2) cos^(2)theta`.
Hence change in acceleration due to gravity is given as
`Delta g = g-g' R omega^(2) cos^(2)theta`,
at equator `theta = 0`
`= 6.4xx10^(6)xx(7.27xx10^(-5))^(2)`
`= 0.0338 m//s^(2)`
