Question
An object weighs 10 N at the north pole of the Earth. In a geostationary satellite distance 7R from the centre of the Earth (of radius R), the true weight and the apparent weight are -
Options
A.0 N, 0 N
B.0.2 N, 0
C.0.2 N, 9.8 N
D.0.2 N, 9.8 N
Solution
g′ = 
; W′ = 
= 0.20N
Apparent weight of the rotating satellite is zero because satellite is in free fall state.
; W′ = = 0.20NApparent weight of the rotating satellite is zero because satellite is in free fall state.
