It would be zero. the weight of an object is maximum at the surface of the earth as you move the body closer to the centre of the earth the mass of the earth between the centre of the Earth and the Body Keeps decreasing. This causes the force acting from the centre of the earth on the body to decrease.

plz prove with w=mg

hey mate!! here is ur answer.
value of g is maximum on the surface of the earth because as we move vertically upwards, the distance R goes on increasing from the center of the earth since
g=1/R²
the value of g would go on decreasing and finally zero at certain height
as we go downwards in the deep valley or mine, we move closer to the center of earth as the formula doesnt hold good in this situation. hence it is concluded that the value of g is maximum on the surface of earth
we have shown that g= 0
we know that W=mg
then, W=m(0)
W=0
hope this time it helped u (☆^ー^☆)

as u say d=0 the by the formula it must be infinite
wait a min, i think i should refer by course book
yes the ans according to books it is 0 everywhere
but by newtons law this is not so
as w=GMm/d^2. then w=GMm/0. So it must be infinite. if u think i am correct then say something and next day ask to ur teacher
by above we concluded that g is 0 then u can show with W=mg
hope it helped u and cleared ur doubts, gd luck with ur studies
