Question

18. The force of attraction between two bodies varies
directly with the product of their masses when the
distance between them is constant and varies
inversely with the square of the distance when the
product of their masses is constant. The force of
attraction between two bodies whose product of
masses is 128 and are separated by 4 units is 512.
If the product of the masses changes to 64 and the
distance between them becomes 8 units, the force
of attraction between them becomes​

Answer 1

Step-by-step explanation:

As per Newton's law of gravitation, the gravitational force of attraction between any two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Hence, the force of attraction between the two bodies
