Question

Which of these objects do you think would exert the most gravitation force on you?

1) a 1000-kg car parked 10 meters away from you
2) a 70-kg friend standing 5 meters from you
3) a 10-kg dog sitting 1 meter from you
4) none of these would exert a gravitation force on me
5) all of these would exert the same amount of gravitation force on me

Answer 1

The 1000-kg car would exert the greatest gravitational force due to its larger mass relative to distance, but all objects exert gravitational forces, albeit small in magnitude for light or close objects.

Step-by-step explanation:

The object that would exert the most gravitational force on you among the options given would be the 1000-kg car parked 10 meters away from you. The force of gravity depends on the product of the two masses and the inverse square of the distance between their centers (as per Newton's Law of Universal Gravitation). Therefore, an object with a larger mass at a given distance will exert a greater gravitational force. All listed objects would exert a gravitational force, although the magnitude of this force would be considerably small for the lighter objects and those closer to you due to the small magnitudes involved.
