How does the force of gravitation between two objects change when the distance between them is reduced to half?
Solution: We know that According to the law of gravitation, the force between any two objects of mass M and m is directly proportional to their masses and inversely proportional to the square of the distance between them.
So, if Distance is halved, i.e new r=2r
So, New F=G22r2Mm
So, Force of gravitation increases by 4 times when distance reduced by half
