As observed from earth, the sun appears to move in an approximately circular orbit. For the motion of another planet like mercury as observed from earth, this would

a) be similarly true

b) not be true because the force between earth and mercury is not inverse square law

c) not be true because the major gravitational force on mercury is due to sun

d) not be true because mercury is influenced by forces other than gravitational forces

Answers (1)

The answer is the option (c) The universal law of force of attraction is inversely dependent on the distance between them. For mercury, this force due to the sun is exceptionally large than that due to earth. Due to relative motion of sun and earth with mercury, this would not be true.
