Explanation
Because earth rotates from west to east direction.
As a rotation of earth takes place about polar axis therefore, body places at poles will not feel any centrifugal force and its weight or acceleration due to gravity remains unaffected.
According to Newton’s law of gravitation, every body in this universe attracts every other body with a force which is inversely proportional to the square of the distance between them. When we move our finger, the distance of the objects with respect to finger changes, hence the force of attraction changes, disturbing the entire universe, including stars.
Kinetic and potential energies varies with position of earth w.r.t. sun. Angular momentum remains constant everywhere.
Time period does not depends upon the mass of satellite.
Initially the weight of the passenger = 60 × 10 = 600 N
Finally the weight of the passenger = 60 × 4 = 240 N
and during the flight in between some where its weight
will be zero because at that point gravitational pull of
earth and mars will be equal.
