To determine where gravity is greater, we can reference the law of universal gravitation, which states that gravitational force increases with greater mass and decreases with greater distance between two objects.
Given the options:
-
Option 1: less mass and less distance between two objects - Gravity might be somewhat significant due to less distance, but the mass is also too low.
-
Option 1: less mass and more distance between two objects - Both factors (less mass and greater distance) lead to weaker gravity.
-
Option 2: more mass and less distance between two objects - This scenario will produce the strongest gravitational pull due to the combination of greater mass and proximity.
-
Option 2: more mass and more distance between objects - While the mass is great, the increased distance weakens the gravitational pull considerably.
The best explanation is Option 2: more mass and less distance between two objects, as this creates the strongest gravitational force according to the law of universal gravitation.
