The mass of the Sun is approximately 333,000 times that of theEarth, and the mass of the Earth is 6 * 1024 kg. TheEarth orbits the Sun in (approximately) a circle of radius 150million km. Let’s say an asteroid of mass 1000 kg happens to beorbiting the Sun in a circle of the same radius as theEarth, but the orbit is tilted relative to that of the Earth asshown here:
The distance between the asteroid and the Earth could be large(a) or small (b). When the asteroid gets too close to the Earth, itwill be deflected by Earth’s gravity.
(a) If the asteroid feels only thegravitational force of the Sun, then this force is [Select from “2”, “4”, “6”, “8”] Newton (pick the closestanswer).
(b) If the asteroid is at a distance of 250,000km from the Earth, the force it feels from the Earth is [Selectfrom “2”, “4”, “6”, “8”] Newtons (pick the closestanswer).
All distances above are measured between the centers ofmass.
