Show that if the earth were not rotating about its axis the value of `g` at the equator would exceed its present value by `3.36cm//s^(-2)`. Given the radius of earth `= 6.371xx 10^(6)m` . and angular speed of earth `=7.27xx10^(-5)rad//s^(-1)`

Text Solution

Verified by Experts

'g'=g-R`omega^(2)`sin^(2)`lambda` At lambda `lambda`=0,cos`lambda`=0 g'=g-R`omega^(2)` `delta`g=3.36 '
