Which objects exert gravitational force?
A Only objects that are close to each other exert a gravitational force?
B Only large mass objects exert gravitational force on objects near them.
C All objects exert a gravitational force on all other objects
D Only large mass objects exert gravitational force on other object
C All objects exert a gravitational force on all other objects
The correct answer is C: All objects exert a gravitational force on all other objects.
To understand why all objects exert a gravitational force on all other objects, we need to refer to Newton's Law of Universal Gravitation. According to this law, every object in the universe attracts every other object with a force called gravitational force.
The magnitude of this gravitational force depends on two factors: the mass of the objects involved and the distance between them. It is important to note that the gravitational force between two objects decreases as the distance between them increases.
So, while large mass objects may exert a stronger gravitational force due to their greater mass, all objects, regardless of their size or mass, have some gravitational force. Even very small objects, like atoms, have a minute gravitational force exerted on them by other objects in the universe.
Therefore, it is incorrect to say that only objects that are close to each other (Option A) or only large mass objects (Option B or D) exert a gravitational force. The correct statement is that all objects exert a gravitational force on all other objects (Option C).
