a. For the two objects that attract each other gravitationally, if the distance between their centers is cut in half, the gravitational force doubles.

The correct option is C.

b. For two objects, with masses m₁ and m₁ originally a distance r apart whose initial values of the gravitational force is f. When the masses are changed to 2m₁ and 2m₂, and the distance is changed to 4r,  the magnitude of the new gravitational force is f/4.

The correct option is B

What is the magnitude of the gravitational force between two objects?

The magnitude of the gravitational force between two objects is given by the equation below:

F = Gm₁m₂ / r²

where;

  • F is the gravitational force between the objects
  • G is the gravitational constant
  • m₁ is the mass of one object
  • m₂ is the mass of the second object
  • r is the distance of separation.

The gravitational force then is directly proportional to the masses and inversely proportional to the square of the distance of separation.
