Answer 2

thanks
can u giv me the reason?
has this got to do anything with the mass of the bodies?

Answer 3

The Force applied by earth on the aluminium is same as the force applied by aluminium on earth.
\[F=G\frac{m\times M}{r^2}\]
But mass of earth is much greater than mass of aluminium , so earth moves very less distance( close to zero) but aluminium accelerates very much .
