WHICH WILL BE THE CORRECT ANS.? (Question: 483303.0 )

Explanation and answers in the options is not matching...

Question:

Two bodies kept at a certain distance feel a gravitational force F to each other. If the distance between them is made double the former distance, the force will be-

Options:
A)

F/4

B)

1/2F

C)

4F

D)

F

Solution:

Ans: (a)

Gravitational force

F=G×m1m2d2    

where F is the gravitational force,  m1 and m2 are the masses of two objects, G is the universal gravitational constant and d is the distance between the two objects. 

Since the gravitational force is inversely proportional to the square of the distance, if the distance between the two bodies is double, the force of gravity is reduced to one-fourth its original value.
