Homework Statement
Question : All things being equal, the acceleration due to gravity is less at the equator than at the poles. Explain why. (from (NZ) NCEA Physic Scholarship (lv4) practice paper.)
The confusing part about this question is that it states "all things being equal". What...
Thanks man, I totally forgot the most important fact about the geostationary satellite XD
Working:
so period of orbit = 24hr = 86400s
using derived formula - T = sqroot((4 pi^2 r^3)/(GM))
r comes down to 42250474.3m
therefore height of satellite from ground = 42250474.3 - 6.37x10^6 = 3.60x10^7m...
