1.	As observed from the earth, the sun appears to move in an approximate circular orbit. For the motion of another planet like mercury as observed from the earth, this would
Answer» be similarly true not be true because the force between the earth and mercury is not inverse square law not be true because the major gravitational force on mercury is DUE to the SUN not be true because mercury is influenced by forces other then gravitational forces SOLUTION :`implies` The reasons are : (1) Relative MOTION between the earth andmercury. (2) Major gravitational force on mercury is due to the sun.
