Detailed explanation-1: -The gravitational force is an example of an inverse square law, meaning that the force drops with the square of the distance. This means that if the distance is doubled the gravitational attraction is four times less.
Detailed explanation-2: -The farther apart the masses are the smaller the force. Because the force is proportional to 1/d2, If we double the distance between two masses, the gravitation force is not halve but 1/4 of the original value.
Detailed explanation-3: -F= Gm1m2r2 where G is the universal Gravitation constant. If the distance is increased 4 times that introduces a factor of 42 in the denominator, to cancel that out, one of the masses must be increased 16 times so that the gravitational force between them remains the same.
Detailed explanation-4: -When the distance between two objects increases, the force of gravity decreases.
Detailed explanation-5: -If the distance between two objects is doubled, then the gravitational force between them is reduced to 1/8th of the original value of force.
