Question

how does the force of attraction between two bodies depend upon their masses and distance between them? a student thought that two bricks tied together would fall faster than a single one under the action of gravity. do you agree with this hypothesis or not ? comment.

Answer 1

F=Gm1m2/r^2

m1 and m2 =their mass respectively

r=distance between them

I am not agree.accleration g=constant for all body

Answer 2

This is the Newton's gravitational rule According to the rule every body in the universe attracts every other body with a force of attraction which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
I am not agree because acceleration due to gravity is constant for every body.
