thz very much, the obversed gravity g' is less than ture value of g =10ms^-2 .
But I can't find the equation of g' in term of g & "angle of a" & "r"
& angluar velocity W only,
help me again pls!
When an observer stand on at the place with a angle "a" of the latitude,
the observed value of the gravity will be affected by the motion of the rotation.SO what is the value of the obversed gravity at that time?
