Objects 1 and 2 attract each other with a gravitational force

of 18.0 units. If the distance separating Objects 1 and 2 is

changed to one-half the original value (i. e., halved), then the

new gravitational force will be units.

    Answer: The new force will be 72.0 units.

    Explanation: The gravitational force between two objects can be written as:

    F = G*m1*m2/r^2

    Where G is the gravitational constant, m1 and m2 are the masses of both objects and r is the distance between them.

    Now, we have that F = 18.0 units.

    Now, supose that we change r to r/2, the new force is:

    F' = G*m1*m2 / (r/2) ^2 = 4*G*m1*m2/r^2 = 4*F = 4*18.0 units = 72.0 units
