a stone mass of 2.5kg is falling a certai height. Find the force of attraction between the earth and the stone. Also find its acceleration

Answer 1

if near earth surface
F = m g = 2.5 * 9.81 N
and acceleration is g = 9.81 m/s^2

if at great distance r from earth center you need to do
F = 2.5 G Mearth/r^2
so a = G Mearth/r^2
