Explain why

Asked by  | 14th Oct, 2009, 09:46: PM

Expert Answer:

If we are on the surface of the earth all mass of the earth pulls us towards it's centre, but when we go deep into the earth, the effective mass of earth that pulls us towards the centre is only that below our location and is less than the entire earth mass. Hence the gravitational force decreases.
