Question

A stone of mass 12 kg falls on the Earth’s surface. If the mass of
the Earth is about 6 × 10^24 kg and acceleration due to gravity is
9.8 m s^-2 , calculate the acceleration produced on the Earth by the stone.

Answer 1

the acceleration would be 1.96*10^-23
as Ma =mg
as here M=mass of earth
and m=mass of body
