An object weighs `10 N` at north pole of Earth. In a geostationary satellite distance `7 R` from centre of Earth (of radius `R`), what will be its (a) true weight (b) apparent weight?

A

0 N, 0N

B

0.2N,0

C

0.2N.9.8N

D

0.2N,0.2N

Text Solution

Verified by Experts

The correct Answer is:
B

`g'=(GM)/((R+h)^(2))=(g)/(49),w'=(mg)/(49)=(10)/(49)=0.20N`
Arrarent weight of the rotating satellite is zero because satellite is in free fall state.
