Question

A body is dropped by a satellite in its geo -stationary orbit.

• A. it will burn on entering in to the atmosphere
• B. it will remain in the same place with respect to the earth
• C. it will reach the earth is $24$ hours
• D. it will perform uncertain motion

Answer 1

Answer: (B)

it will remain in the same place with respect to the earth

Geo-stationary satellite are those which have same angular velocity as that of earth, so they appear stationary with respect to earth. A body dropped off from satellite would also have same velocity as that of satellite, and so the angular velocity of the body would be same as that of earth also. So it would also seem stationary with respect to earth.
