In order to understand Gravity at locations we have no access to 'Earth's Core', one can perform Gravitational experiments in the opposite direction, and thus deduce from experiment the of "g" over certain distance's.Aladin said:How varies the value of "g" in the depth of the earth.
the value of "g" at sea level is 9.8m/s2 what will be the value upward and downward the centre of the earth.
I know that at the centre of the earth the value is zero.
Please explain.
thanks
