Question 1.How does the force of gravitation between two objects change when the distance between them is
reduced to half
Answer. According to the law of gravitation , the force of attraction between any two objects of mass m1 and m2 is proportional to the product of their masses and inversely proportional to the square of the distance 'R' between them.
Answer. According to the law of gravitation , the force of attraction between any two objects of mass m1 and m2 is proportional to the product of their masses and inversely proportional to the square of the distance 'R' between them.
As given here  F = 
Gm_{1} × m_{2}

R²
