Detailed explanation-1: -So although the object is pulling the earth towards itself, the earth will not move because its acceleration is very, very smart. So are correct option will be the Earth has ready large mass and small acceleration.
Detailed explanation-2: -Gravitational Constant Force: The Earth pulls the falling objects with a constant force and so do the falling object on Earth but the Earth-size is considerably large and therefore, the pull due to falling object was seen significantly. In other words, the Earth is also actually falling towards the considered object.
Detailed explanation-3: -It spins (rotates) at a speed of about 1, 000 miles (1600 kilometers) per hour and orbits around the Sun at a speed of about 67, 000 miles (107, 000 kilometers) per hour. We do not feel any of this motion because these speeds are constant.
Detailed explanation-4: -You do pull the Earth, but because the Earth has a very large mass, it accelerates much more slowly.
Detailed explanation-5: -Apple falls towards the earth, but the earth does not move towards the apple because acceleration is inversely proportional to mass. Earth’s mass being extremly large as compared to apple, it has negligible acceleration towards the apple.
