How does the force of attraction between the 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 his hypothesis or not? Comment.

This hypothesis is not correct. The two bricks, like a single body, fall with
the same speed to reach the ground at the same time in case of free-fall. This
is because acceleration due to gravity is independent of the mass of the falling
body
